Yeah, there's a whole string of manuscripts using this "one leg up" pose, though I'm not sure where it comes from or to what extent it can be considered standard.
Either way, if you google images of swans or geese you'll often see them in this "stretching towards the sky/about to take off" pose, which is also rendered in many constellation illustrations. That's what I think the nymph's pose alludes to, of course reinforced by the feather-like hands.

I've still got no hypothesis about the other figures by the way, haven't had the time yet to study them in depth. For a while I thought the one all the way on top had to be Virgo because of the "spica"-like attribute, but there's not much else pointing that way so I'm not happy with that. She'd also be out of place in the Hercules group.
