Mixes, none really look purebred to me.
Big red doe looks like she has a lot of boer in her though.
Doe in the 4th picture has a alpine look to her.
Does in pic three look like boer N dwarf crosses.
The pure white one looks like a saanen cross.
I think the fourth one has Nigerian Dwarf because of the blue eyes and spotting. The ears probably come from Boer or Nubian. The one with the frosted ears probably has Nubian, I don't know of another breed that has those.
