I would say the white hen and non-bearded hens are likely easter eggers, but your third pictured one could either be a silver ameraucana or an easter egger of the same color.
Your white hen looks to not have a pure peacomb, it looks to have points like a straight comb, but is very floppy.
The middle hen pictured is not any recognized ameraucana color, nor is she bearded. In some lines, non-bearded ameraucanas might pop up, but her coloring is incorrect for even a silver ameraucana, so she's most likely a cross.
As for the last, she's bearded and has a peacomb. Whether or not it is pure peacomb I cannot tell. Her coloring looks very similar to silver ameraucana coloration, and she has slate legs so I would imagine that is what she is.
