from top to bottom,

the left side is:  Aruru, unknown red haired girl, Misaki, Youko, Dina

The right side is: Haru, unkown mantis girl, Bima, Unknown silver haired girl, Froze

So there's 3 unknowns and Horo and Froze then adding on the Melusine will be 6. I'm not sure if that silver haired unknonw girl is Horo. The hair ornament doesn't match, but it's not entirely impossible xD
