Are these plants androgynous?

A bit small to be certain. You could pull those out, split them open and look for white hair inside before you can discern a difference as it grows. You'd need some magnification, of course, but the 'fuzzy white hair' under a scope is impossible to confuse with nanners inside. You have a ton of time to figure this out. Be certain because throwing out a plant is usually a big deal in a small garden. You have no concern for pollination at this stage, so you can be patient identifying.

Yes this looks like a Hermie. You can keep the plant and remove the pollen sacks and look out on a daily basis if new ones emerge, if this is one plant from many i would toss her or at least isolate her from the others, if its your only plant i would keep her

Pic 1.......not entirely sure, but I don't think its a male flower. Pic 2 ..........certainly looks like male flowers coming.
