Bantams? I need help sexing and finding out the breed!!

[brailipearson]

These are my other two of what I believe are Banties. They are quite bigger than the cochin pullet I asked about previously. The black/yellow/white one has extra toes. These ones do not have feathered feet, as you can see. They are a little aggressive towards eachother and I don't know the sexes of them. Help?

They are polish.

I am not sure but it in the second-last picture it looks like some sort of mixed breed of a silky and a French black copper Maran.
