Honestly, I think this kind of listing would probably end up pretty dull in the end as, like, 90% of the cast is Chaotic Neutral: they're all prone to just kinda doing what they feel like doing in the moment and only thinking about the repercussions afterward. Usually after those repercussions have already happened as well. Some of them try to do the right thing more often than not, some of them consider what feels to them like the right thing (these are two similar but different concepts of "right"), but most of the time they're just sorta...reactionary.
Momo's a clear exception, I'd agree with the earlier Lawful Good suggestion for her.
Hanners is more difficult to categorize; her condition and self-imposed "laws" it applies might suggest Lawful, but given she actively tries to break those "laws" by challenging herself to overcome her limitations, I'm not sure it's really accurate to describe that as her inherent alignment.
Marten, being among the characters least prone to extreme things and worrying about whether he's stepping on any toes in the progress after the fact, is probably closer to true neutral than chaotic. Crossing the country on a whim might seem pretty random, but it's perfectly legal and, more importantly, it was motivated by a fairly restricted interpretation of his living situation, in a sense: he wasn't doing it just to do it, he was doing it because he felt like he had more reason to follow the girl than stay where he was. In essence, it was the opposite of a "wild and free" decision. It was more like being tugged to the east coast on a leash, even if the leash was only in his head.
Most of the other characters, just off the top of my head? Yeah, chaotic neutral across the board.
