This would just be a guess, but it looks like your first four all have a bit of Japanese in them. They almost look like attempts at breeding some Japanese into Serama. The top rooster is Blue Red in color, the second almost looks Red Pyle (can't see chest to know for sure), the next is Birchen, and the hen looks off-white to me. Finally, the next hen down has a Columbian/SilverQuail base pattern, a beard and single comb. I cannot see her legs, but I am going to guess they are feathered. My best guess would be Columbian d'Uccle or a mix of a D'Uccle.
