First pic is a black copper Marans. Looks like the same bird in pic 2 and 3.
Fourth pic is an Easter Egger.
Fifth photo looks like someone crossed breeds but I could be wrong. It has a rose comb, feathered legs and is barred. I can't tell if someone crossed a Brahma with a Wyandotte or some other stuff.
Next photo Blue Copper Marans and maybe a Cuckoo Marans
