So, what have I got? :/

First one is a black sex link or Red Rock Hybrid.
Not sure about the second.
Doubt the third is a dominique...
Last one might be a mix.

They all look like mixes to me.

 

[drumstick diva]

me too

Second one looks blue to me. With slate legs and not a sexlink. I'm thinking marans in there.

Edit to add: agree with junbuggena and diva - mixes

The second one looks kinda like a blue copper marans, but like the experts say, probably a mix. I think barred rock for the third; one of mine has a comb that big. Pretty girls!
