yes. through hawking radiaiton, as they radiate particles these particles should also take some angular momentum with them. however i do not know if it would ever be enough to actually stop a black hole from spinning. and currently the universe is too warm for black holes to radiate unless they are extremely small, and so far extremely small black holes are only a theoretical object.
"while a mass contracts, its rotation will develop." sounds like it is asserting, while a apple falls off a tree, it hurries up in the direction of the floor. A Newtonian physics pupil might ask (by way of fact scholars are stressful and that they like to invite difficult questions) "If the apple fell and the floor wasn't there, might it basically save going quicker and quicker perpetually?" nicely, all of us understand that won't be able to ensue. Even Newton might desire to describe why it does not. Einstein might swing at a different pitch, however the respond may be the same. "while a mass contracts, its rotation will develop." Does it? An assumption of conservation of Angular Momentum means that occuring, yet at what factor does Einstein initiate beating on the door and remind us that what's being conserved is capability, not rotation? A smaller mass shifting at relativistic speeds might earnings capability via cave in, yet not develop rotation by skill of plenty, the nearer you get to c. As Yogi Berra might have suggested, if he have been a Physics theorist... "it is Tau 0 as quickly as greater."
No. In fact the rate of spin grew as the original star collapsed into a black hole. Think of an ice skater spinning. When they pull their arms in, the spinning speeds up dramatically. The same thing happens when a star collapses.

Sure. You can reduce the angular momentum of a black hole by throwing stuff into it that has the opposite angular momentum.

Black holes only grow larger, except for microscopic black holes. They dissapate faster than they eat stuff.
no. they only grow.
