Pyrrha's Semblance is implied to only work on metal she has touched, hence Mercury's line about how she could move his boot around "after she made contact with [his] boot". That may be why Monty did that animation with the soda cans where Pyrrha slammed her hand on the soda and transferred her Semblance through the spilled soda into the cans.

Emerald can only use her Semblance on one person. If she uses it on two at the same time, she gets a migraine. We don't know what happens if she uses it on more than two.

I think the Aura drain thing really is already a mechanic, since we didn't see Emerald get hit a single time in her and Mercury's tournament fight against Coco and Yatsuhashi, and yet Emerald had less than 100% Aura, as displayed by the scoreboard when Coco watches an instant replay of Yatsu getting disqualified, which was after Emerald had used her Semblance to make a fake Yatsu.
