well at least two of them are in healthy relationship with their parents
I do too, its a very personal subject for me and I want to see a story where we're actively working on not adding to abusive cycles but rather healing and being better. 
In the case of Jekyll, his parents were very negligent of him as they had a kid for fun, but lost interest when they became bored/annoyed with parenting. With that said, his parents and him don't talk. As for Hyde, he doesn't have any because he came from Jekyll's soul.
Warrick's relationship with his creator who can be called his mom is great. They get along well and clearly are close. She is very doting on him and in return, he takes care of her. Or rather, he did before he went into his coma and woke up 500 years later. As for Stella, the parental figures in her life were her grandparents and they were extremely good to her.
Word's "dad" is his owner James and he's a very loving one to him which is the point of the story really.
Adi has a good relationship with her adoptive parents (even if they don't really understand her). She doesn't know who her birth parents are, but has a lot of questions for them if she ever finds them.
Koreal (who has not yet made an appearance in the comic)... was disowned by his parents, so that relationship is, at best, non-existent.
Kerren had a great relationship with his parents (until insert spoiler here )
now his parental figures include Mrs. Calloway, and Marrick.
He loves Mrs. Calloway, feels like he's disappointed her though. Marrick... it's complicated. he pretty much just like.. lives with him??? like now (specifically like chapter 7 time) it's kinda an indfference.
Summary
putting mine under a read more owo;
Dutch: Doesn't really talk to his parents much, these days. He's not estranged from them or anything; he's just been away from home long enough that the most contact he has with his parents are a couple letters he writes to them a month.
Alex: Only has vague memories of his biological parents: they were killed in a head-on crash when he was very little. His aunt Betty took over as his guardian soon afterwards, and he's pretty close to her.
Lee: Thinks that his mother is the definition of a tiger parent, which annoys him, but he's still close to his parents.
I'll go with the characters introduced so far.
Lucy: Doesn't have a good relationship with her mother but I can't reveal why just yet. She has a good relationship with Solomon, she thinks very highly of him and sees him as her father figure.
Jack: Has a great relationship with his parents and wants nothing more than to see them again.
Mel: Never knew her parents but I hope to reveal that soon.
Norman: Never knew his parents, but Adrielle, his aunt, is raising him as if he were her own. They have a great relationship but Norman is kind of a weird kid and she doesn't understand him sometimes.
Vincent: Hates his mother with a burning passion because she was part of a cult and contributed to sacrificing him.
Well, my main character does not have a good relationship with them, like at all. The result of very narcissistic parents with a heavy preference for his sister. Him and his sister have a close relationship tho!
It's still to be told in the story, but my main character's parents divorced when he was 10, his father left town and hadn't seen him in six years, plus he barely called or texted him. Now he's 16, he had to move to the town his father lives to play hockey and they reunited, but although he tries a lot to get along with him, the old man keeps the distance and seems not to care at all about his kids. But I'm still building this relationship.
Another one has a close relationship with his father, but the old dude is too harsh and demands a lot from the kid.
In order to have a relationship with their parents, they should still be there.
This is valid for both the main characters, Annie and Scott. Victorian times were tough.
Despite this, Annie's father figure, uncle Scott, is always with her and they are quite connected in life. There is a good synergy between the two and an average of 20 years of difference, they have grown up and fought the difficulty of life together. 
My main characters don't have the best relationship with their parents. It's more they tolerate each other. For two of them though, as they get older they have a much better relationship with one of their parents.
Agony: very negative, can't reveal for plot reasons, but real bad.
Thesis: fine? Fine.
Duenna: got some not great influences and ideas passed down, but overall loving
Motif: kinda lonely, parent's worked a lot
Sequel: very supportive! little but of favoritism towards his brother, but not bad
Forces Of Nature: The Season Sisters have a pretty good relationship with their parents. Autumn is especially close to their father and as is Spring with their mother.
Their brother Dry sometimes isn't on best terms with them due to his antics and feeling overshadowed by his sisters, but at the end of the day they still care for each other very much.
Rainy has a good relationship them as well, but tends to be moody and withdrawn at times which worries their mother
Circus Freaks:
Asa has very good relationships with her parents. She's a bit spoiled and admires her father a lot.
Mimo doesn't remember his biological parents, but is very close to his adoptive ones, his mother especially.
Mago... uh... well... it's complicated...
Right now Andrew has a good relationship with his father, and though his mother died when he was younger he's got no issues with the woman who is soon to be his stepmother. Though it's implied in the story that in the future his relationship with his father is terrible, to the point he's cut himself off from him and the rest of his family, and when questioned about him 'has nothing good to say about him.'
@fleurravenbooks nice to meet you again, we subbed each other, but hope it's ok I join 
Keep up the hard work and hope you gain more subs 
Owen Moriarty: has a loving relationship with Evlyn (mom) and Doland (dad). His parents have always been supportive of him. He shares similar hobbies with his father. While life at home is usually peaceful, he does feel hurt when his dad and big brother Evan get into arguments. As a 13 year old boy the story reflects his transition from following his parents' decisions to making his own decisions.
Evan Moriarty: in his childhood he had a good relationship with his parents. His real father Lachlan went MIA leaving an Infant Evan and his mom Evlyn behind. Lachlan's brother Doland stepped in to assist Evlyn and the two eventually fell in love/ married. Doland and Evan had a good relationship initially, till Evan felt Doland was too dominating. (Doland and Lachlan had a close bond) Evan and Doland have strong, contrasting personalities that evolved into arguments. This caused Evan to drift away from his family. He loves his mom and brother but hates Doland. He may also be annoyed that his mom allows Doland to take charge in decisions.
Xun : he is an orphan with no memory of his parents
Amèlia: she's got a good relationship with both her dad and her mum, maybe she's a bit closer to her dad, as she was always his favourite of their two daughters 
Lucifer: it's complicated and I can't say much because spoilers; I just can say if there's something like a dad to him, the answer would be eternal hate
Tumael: "who the hell are even my parents and where do I even come from?"

A very interesting one bc it's also kind of important for my Main Character !!
Toby has a bit of a complicated relationship with his mother.
He loves her dearly and does everything in his power to support her, since her job barely covers the neccecities and she suffers from severe depression and alcoholism. But at the same time, Toby doesn't like being around her, bc she can be very gruff and mean and doesn't show a lot of affection towards him. it's why Toby rather stays outside in his free time than be at home.
Since his father vanished when he was 3, he has no memory of him.
Both of them are dead. The former king and queen of claran https://m.tapas.io/series/The-Prince-of-Claran-2
Rob: His relationship with his parents is good. They're pretty much in the background and his mom is the main one to show up in the series so far, but they offer him support when necessary.
Daniella: Her and her dad have a bit of a strained relationship due to him moving them from New York all the way to a small town in Texas. Daniella doesn't fully understand the full meaning of why he did this and how much she may have needed the change, so she sorta resents him.
Henry: His parents are constantly at each other's throats, so Henry doesn't have a very high opinion of them at times. He wants them to stay together and he hopes that he's enough to keep them from splitting apart, but he feels deep down he may not be enough.
This one would be a big Yikes for my MC. Right now he has no memory of his childhood due to amnesia but once he remembers his youth, especially his family, he's going to wish he hadn't. So, whilst in the spirit of trying not to let loose some important future story bits. His relationship with the one parent he did have in his life was not good at all.
My story(web novel):
Inspired by works such as Ghost in the Shell, Ergo Proxy, Serial Experiments Lain, and Akira, Technocyte: Beyond Human follows Detectives Beatrice Alice Moreau and Jay Lee Jones, an amnesiac man named Sherlock Lawson, and a mysterious young girl named Mina in a cyberpunk/ dystopian like setting as they uncover the truth behind Sherlock's elusive past and his connection to the Technocytes, enhanced humans who are able to morph metal around their bodies and manipulate technology, and the organization responsible for creating them known as SANCTUARY.

My oc neon has a good relationship with his mother but not with his father and brother (they don’t approve him being into guys) and my oc Alioth has a good relationship with both of his parents
Well, both of Kovreil's parents died when he was a kid... but he did have a good relationship with them when they were alive. They were very caring parents and he still fondly remembers them all these years later, even though his feelings towards his childhood are quite complicated.
Well...
Jade: Doesn't know her parents! She's dead, and can't remember anything about them really. But sometimes, when she's lonely, she thinks that she can feel a hand on her shoulder, or someone saying something softly. Never anything exact, but it's there.
Jaime: His mother passed away early in Jaime's life, so he doesn't really have any memories of her. His father RamĂłn, however, he was very very close to. The two regularly went camping, fishing, and hiking, and in general spent a lot of their time together. Jaime often forwent trying to get friends his age in favor of spending more time hanging out with him. He didn't take it well when RamĂłn passed away.
He does not have a good relationship with Jude.
Polela have a great relationship with her mom but don't know her dad (because he left after mating season cause that's how polar bears life cycle works and sadly if a random male polar bear finds a den with the mother and cubs they'll eat the babys if they successfully got pass the mother bear [I think]). After Polela have left, her mother develop a relationship with her best friend and dated for more than 4 years afterwards. Polela knew about it because she get calls from them often and it becomes part of her daily basis when she get calls 5 times a week so she have to keep a phone on her that all times so she doesn't miss them.
