Where did you get them? Some look like mixes to me.
first-silver laced wyandotte hen
second--some splash bird. The feather legs could be marans but the body looks awful light for a marans and I can't see the head.
third--mixed breed, with some barring or cuckoo in there somewhere. It looks male to me, but age is the key there.
fourth--maybe mixed, maybe australorp
I agree the red bird may be an ee, or ee crossed with something else. If that's a pea comb, it may lay green eggs. Although, it almost looks like hackle feathers? I can't tell if it's just the color or not. Again, knowing how old the bird is would help.
