The belly marked one might be a het pied. I know I sell possible het pied males as normals. But to be sure if you are working on a pied project before risking wasting a year for a valuable het pied female you should buy a 100% het pied male as they are very affordable now days.
The "normal" girl looks the least normal of the bunch to me. Probably nothing but I'd hang on to her and breed her just in case.
