Tested the first two, guessed the others based on subtype/roles:
Alec Tryon: ESTJ (Executive, which fits!)
Luke Tryon: ISFP (Adventurer, open-minded, creative? Eh.)
Aldi Zemay: INFP - diplomatic, good cause(vegan)
Horace Apis: ESFJ- Consul (Mr helper)
Carl: uh, don't know. Brain mostly empty.
Friar: INFJ (He'd be an ENFJ type if others actually listened to him, lol)
Bucky: ESFP? (he's the village idiot, but fun)
Gallus: ENTJ (leader/commander)
Dr. Fowler: ISTJ (logistan, well, he's a doctor)
Maybe I'll update this later when I feel like taking tests for each character
Might never be 100% accurate, cause some are bound to change through story. Still a fun idea to help build up future chars.
