Actually an Araucana is a true breed that has a tailless rump and lays blue eggs. Easter Eggers are hybirds produced by crossing blue egg layers with brown egg layers to produce offspring that lay eggs in colors other than just blue. Hatcheries and feed stores often and incorrectly market their EEs as Araucanas or Ameraucanas, when they are in fact EEs. Since Easter Eggers are hybrids, they do not conform to any standards, including the color of their legs, although EEs commonly have greenish legs and pea combs (but not always). There is a good article at http://www.the-chicken-chick.com/2011/09/ameraucana-easter-egger-or-araucana.html explaining the difference between Araucanas, Ameraucanas, and Easter Eggers.
P.S. Sorry I forgot to address the issue of the other bird. I agree with junebuggena; it's a mixed breed, probably a Cochin mix given the feathered legs and single comb.
