I answered for my main, but now for my alts:
Michaux's first name was simply chosen from a list of French surnames. I liked the sound of it. His surname, Vidal, is the name of a rakish, wild, unruly character from one of my favorite books. I chose it because I planned to loosely base Michaux's personality on that character, but I ended up going in a completely different direction with him instead.
Leonie actually has two names. Her birth name was Eve Renardier. There's a simplicity and purity to the name Eve that seemed to suit Leonie's younger self, but there's also something just a touch ominous about it, given the Biblical story of Eve's fall. Renardier means fox hunter, which has nothing to do with anything, except that I happen to like it. Leonie Daucourt is her assumed name. Leonie is a name I'm particularly fond of. It means lioness, so it is associated with bravery. I chose it specifically because she is haunted by an act of cowardice in her past. There is irony in the selection, but also a bit of hope for her eventual redemption. And Daucourt is another name that I simply liked the sound of.
Tatsu Kaisuri is a name I... slightly regret. Kaisuri came from the name generator, since I did not feel capable of picking out a lore-compliant surname for a Raen. But I didn't like any of the first names generated, so I went in search of one. I chose 'Tatsu' because it means dragon. In my defense, I was new to the game at this point, and didn't realize that Au Ra aren't related to dragons. So now the name feels a bit tongue-in-cheek. Oh well.
J'aeda Rhenli is just a combination of letters and sounds that I like. It means absolutely nothing.
