Does anyone know the breed and gender of these

I agree that the black hen is a midnight majesty marans, or a similar marans hybrid.
I can’t figure out the bantams. They have to be mixed, but hatcheries don’t sell bantam mixes. The crested hen and rooster are bantam sized, right?
Do you have a clearer picture of the crested hen?

I do not at the moment but the hen is actually the smallest chicken I have in that coop at the moment
