What are these ladies?

[Dino_Chicken]

I know Red Star can vary quite a bit so I assumed they all are such! I'm just curious though since RIR and a couple other breeds can look really similar. All from our local Murdoch's marked as 'pullets.' 3-4 months old, still doing their teen bird sounds!
There are 4 ladies total:

Lady 1:

Lady 2:

Lady 3:

Lady 4:

Thanks so much for the help! Hope you all are having a wonderful day!

Three and four look like RIRs. I'm not an expert though. @nuthatched
