Individual pictures are helpful.
Barred chickens have white headspots. Male barred chickens have more white on their feathers. It looks like you might have at least one male.
The one in the very back of the topmost picture looks like a silver laced Wyandotte. She (?) should have a flat comb and yellow feet, if so. The ones with slightly more yellow stripes will be your golds. Wyandottes are partridge-coloured, and so are most Easter Eggers, so they'll have similar markings, but the Easter Eggers should have fluffy cheeks.
Fluffy cheeks usually = Easter Egger. I doubt you'll be able to tell those from the Green Queen.
The peach one with the slightly darker back stripes looks like a red sexlink. I see you list red buffs? I would say she is one. It looks like she has an identical sister.
Lakeshore Eggers are apparently descended from Cream Legbars, so if any of them develop crests, they are these.
I don't raise meatbirds and have no idea on their breed.
