Going by the photos you posted,
in the top photo are two girls and one boy: blue girl, partridge girl, red boy.
in the next photo are partridge showgirls. The two in front are girls, the one at the back may be also--I would need to see the plumage to be sure. If it looks that same as the two in front, then also a girl.
You can breed the red to partridge and have decent chicks.
Breed the splash to the blue. I'd have to see a photo of your black boy with red & buff--he may be partridge?
I didn't see the list of your standard hens.
