Flatworms (planaria) can usually grow a worm from each section when they are halved.
Earthworms can not regenerate missing parts. No worm rejoins severed parts. So the answer is NO for coming back together.

Nope, not like your D&D trolls. Certain worm species can grow back, so if you cut a worm in half, one half might survive, or rarely both halves and you'll end up with two worms instead of one.

Moles eat earthworms and, if they aren't hungry, first bite their heads off so they can't escape from the mole tunnel. The mole must return to eat the worm within a few days before the worm grows a new head and digs out.

Not exactly..if you cut a worm below the saddle then the tail will sometimes grow back but it wont rejoin!!!
