Pics 9-10 counting from how they're listed on your post show a white chicken laying on the ground, and also a closeup of her comb. This is a white leghorn pullet.
The ones with the head poofs (not your polish) are either cream crested legbar or olive eggers, I think. These are the two birds in the 5th picture, standing next to and not including the gray chicken.
The bird in pictures 2 & 3 (wild type pheasant coloration with pea comb and colored legs, no white in the feathers like your speckled sussex have) may be a prairie bluebell egger, but I don't see any other PBEs.
