I agree...you've got a lot of genes represented there. The farm that sold the eggs to the store had a lot of birds running around lose, some of which were EE's of the Ameraucana variety as beards/muffs are seen on some.
I see nothing to indicate on any Araucana...rumpless, tufted, yellow legged, more upright stance.
Therefore I think the farm had an EE from Ameraucana background bred over a lot of other birds, that bred as well to produce the crazy, but beautiful, outcropping you've got with feather, leg color, and comb variations. (BTW I love my backyard mixes...they are colorful, hardy, and great layers).
I think (hard to see in photo to be certain as I can tell comb better in person) that your boy almost has a walnut comb, or modified pea.
Combs have 2 genes. Only 1 rosecomb gene is necessary to express rosecomb. Only 1 peacomb gene is necessary to express pea comb. If you have both rosecomb and peacomb, a walnut occurs, or a modified looking thing.
So your boy is probably EE with something else, possibly game. Somebody on the farm had blue legs (the leg color looks Campine in tone color in the photos).
Your girls are a mix of mix with some EE in the mixture, and probably Wyandotte as I see some Wyandotte body type suggested.
Wyandottes would have only rosecomb or single comb. To get a peacombed Wyandotte would take horribly controlled lines with something else in it to add the additional peacomb gene as you would get more walnut rather than peacomb as a natural throw back for birds expressing rosecomb with peacomb added...to achieve pea you would have to remove rosecomb from the line to avoid walnut...which you'd have to work at that with a Wyandotte...or simply have an EE in the Wyandotte bin.
