>If 1 swallows something, does the other feel full?
Depends if they share a stomach or not. Sometimes they do, sometimes they don't.

>If one limp gets touched, which head feels it?
Each head feels (and controls) its side of the body.

Conjoined twins can differ in how far they're conjoined. Sometimes they share organs, sometimes they have their own sets of organs, there's a lot of variety.
