If I were writing these dances, I'd probably give them all the same name and call them #1, #2, and #3, because they have the same overall sense and theme - easier for me to keep track of them. If different people had written them at different times, they could probably call them different names. However, if I wrote one of these this close after seeing one of the others - then I would call it "variant of so-and-so's dance X". 1 and 3 appear to just start in different places, aside from the gypsy to allemande switch. I certainly wouldn't give a new name to that, just call it a variant.
Dance 2 is awkward because of the different amount of gypsying that men and women do. Harder to teach, harder to dance, timing issues in getting back to P at same time. If you are going to have a he-he-she-she wavy line, this is not the best one of these to use, and I probably wouldn't call it. As for 1 vs 3, 1 is the better composition. Starts easy, easier to teach, easier to know you've made the transition and are dancing with new people. The left shoulder gypsy can be a smaller circumference move then the allemande - and this dance is going to have issues with people in tight lines banging into each other. In fact, it might be better to gypsy right the partner, except you have right hands joined so it makes sense to allemande. Ends with the partner swing, more satisfying than ending with women chain. That said, it is only a dance to be called with plenty of space along the lines. Which is another reason #2 is not as good - when you put in a forward and back, it can limit the distance that the couples can get away from one another along the line, making the HHSS line a lot tighter and unpleasant for the allemande and partner swing.
