Yes, bumble bees will sting, but they have to be provoked into doing it.

No, they don't. Unlike bumble bees, honey bees die soon after they sting because their stingers have barbs that make it impossible for the bee to remove it, and instead the venom sack pulls free of the body, mortally wounding the bee. Bumble bees do not have barbs on their stinger, making it possible for the bee to remove it's stinger, and sting repeatedly.
In general, no. But there is a species of Bumble Bee called the Cuckoo Bumble Bee (Bombus vestalis) that is parasitic on existing nests, and will kill by stinging, the original queen.

If a bee stings a mammal or bird, no; the stinger becomes trapped and tears out of the bee's body. If fighting other bees or insects, yes.
