Medusa has wings and snakes for hair. I think those speak for themselves.

Trudy has minor hearing issues, thanks to military career and the amount of explosions, gunfire, and engines she's been around. Also thanks to repeatedly breaking her right shin, it always lets her know when the weather changes.

Kait...hmm, well, her curse does make life a bit hell, but on the awkward side, her sense of smell. Things can make her feel ill quite quickly, and too much perfume can give her a headache.

Esfir is tiny, 4'10. Of course this can get annoying.

Can't think of anything for the others.
