In the decent photo, Prancer looks male, and does in the first photo too. Poppy looks male too. Persia is female. In the collage photo, Picasso looks male.
If I'm right, you've either got a ratio of 3m:2f or 4m:1f. Even if I'm wrong about Picasso, that would still leave 2m:3f, and you will probably find that the females get very stressed from constant amorous attention from the males (and possibly stressed to the point of death). If you have a chance to swap some, try to get all males, as you won't get overrun with fry.
