From a comment:
sauce: Wiz (Konosuba), Chizuru (Why the Hell Are You Here, Teacher?!), Rem & Ram (Re:Zero), Hanako (Katawa Shoujo), Miku (Quintessential Quintuplets), Miyako (WATATEN!: An Angel Flew Down to Me), and as for the red haired girl, this is all I got

I'm not the right person to ask tbh. This is all I could think of and find but not seen these series.
Maybe Ulalala from Space Channel 5 too or so?
