These are very cool, inventive & mystical sounding names!
Re the girls, I’m personally not a fan of repeat starting letters but if they’re not twins, it’s not as eye-twitchy for me (they’re a too matchy Aris and Alis for twins, imo). I like Angelis and -us. They both read masc leaning but maybe the -is is a little more Fem.
I like Trustin - might get some annoying teasing though, esp with Trusty - but it has something solid and rugged about it.
