Well, the alien race in one of my comics purposefully uses names from Earth frequently to name their children. So oftentimes they have an Earth name and an Erkon name (Erkon is the name of the alien race). The character names vary a lot from Giorgio, Mercedes, Copper, Isaac, Cassandra, Voltineria, Dietre, Aneska, Su-Min, Engreli, etc.
The main characters from my current comic are Japanese. I'm not Japanese myself, but I at least am intermediate level (N3) of speaking Japanese so I know a decent amount about it and know if the names really fit the characters.
However, there are other cultures represented in my comic too since it's a very international comic with many countries coming together to fight in a war against aliens. I worry about possibly doing something wrong so I try not to go into much detail.
