I'm not seeing any wattles on your BR and no really red comb, pullet would be my choice but your other 3 are very hard to see.
Your wheaten Amerucuna looks like a pullet but again better pics would help, this one also looks like a salmon faverolle.
Any Ameraucana or Araucana bought at a feed store, or hatchery is an Easter Egger. They are mixed breed birds and the hens will lay varying shades of blue, green, or pink eggs. It is very hard to tell with this picture. Individual close-ups would be easier.
Well the barred rock I was worried was a roo was the first to lay eggs regularly getting small brown eggs. The amerucana that I thought was a hen I just saw lay the egg. I have been getting a few green eggs now for last 5 days one daily.
