What individuals, other than Thor himself, are worthy to hold Mjolnir?

The only one I've seen do it is Wonder Woman.  During a battle Thor was knocked to the ground and lost his grip on Mjolnir.  Wonder Woman picked the hammer up, handed it to Thor and returned to the fray.

Captain America (no surprise there) and the alien Beta Ray Bill.

Most of the people who have been able to wield it are already notable in their own right. Thunderstrike was a nobody until he picked it up. In theory, *anyone* could use Mjolnir short-term if it was for a particularly worthy purpose.
