I honestly am no export, have some hens of my own I'm planning on getting ID'd but on the second to last picture, the two hens facing the camera on their roost look quite a bit like some of my hens that I suspect to be a type of game hen, so maybe they're game bantams, if there is such a thing.
1 is a black tailed buff Japanese bantam, albeit long legged and it is a definate he!
2 looks like a modern game or dark cornish?
3 looks like red pyle old english
4 and 5 i'd guess are oegb too
the white one may be too hard to tell from that angle!
