Like I said before, Raven is not a maran. Marans do not have muffs. She could be an easter egger, but I am leaning towards Ameraucana based on traits. But she could be an olive egger.
The second one looks like the blue maran to me. She has no muffs and feathered feet like a maran should. Below is my terribly conditioned, but blue maran.
I think you have them switched. The first one is questionable, but the others look like pullets.
This is a blue maran, sorry for her terrible shape, this was a few months ago when she was in heavy molt. She is so gorgeous now I am showing her in state national.
