I think that the first 2 birds are straight sizzles. They have silkie combs and other sizzle characteristics like the fluff on their heads. The white one is also a straight sizzle. The last red one is either a frizzle or a sizzle. I can't tell from the pics about the buff colored one but the black one looks like either a black cochin or a black mottled cochin. I hope this helps. 
They are very pretty little birdies.
I have 18 chickens, one kitten, 3 dogs, 2 hermit crabs, and live on 20 acres in the country. I am CrAzY about chickens and plan on getting more! I am continually working to better my chicken practices and to better my flocks.
