Dunno man, those first pics look like it's a male to me. I'm no expert tho, not by a long shot, but if it were me I'd cut my losses and just rip that one out. PLEASE someone correct me if I'm wrong.
As for the rest of them, they're lookin gorgeous. Looks like a nice LST job so far too. I'm planning on extreme LST for my current girl, keep her nice and low and spread that canopy right across the soil.
