This is a black hole formed from antimatter, instead of matter. The only real difference thereby being that the matter within the black hole would have an opposite charge from normal matter. Other than that, an antimatter black hole, while still theoretical at this point, should have properties the same as a black hole formed from 'normal' matter. As with a normal black hole, an antimatter black hole would be created by having enough antimatter to cause a gravitational collapse.
Almost certainly some antimatter would exist in black holes merely by virtue of the fact that space itself does have small amounts of naturally occurring antimatter. High energy cosmic rays can generate them by collision with other particles in the interstellar medium; since antimatter has mass it could possibly get sucked into a black hole if it does not interact with normal matter and get annihilated first. It would be much more difficult to observe than to infer this, however, since events inside a black hole are hidden behind the event horizon and can't be directly observed. There are also mechanisms described by which black holes are thought to generate antiparticles; one arising from random quantum fluctuations near the event horizon in which energy from the black hole's gravity will "boost" the generation of a particle-antiparticle pair; this would not violate principles of conservation since the various properties would balance out. It's been proposed that this is one way in which a black hole could slowly "evaporate"; with one particle being absorbed across the event horizon and the other escaping and thus carrying away energy and very slowly shrinking the black hole per Einstein's famous matter-energy equivalence formula - hence antimatter would be constantly falling in. However, it would be important to say that matter inside a black hole is not "necessarily" antimatter merely because it's a black hole; infalling matter does not suddenly turn into antimatter for example.
If I understand the situation correctly, once any substance gets into a black hole, the distinction between "matter" and "antimatter" becomes irrelevant.
According to Christian Paulhus, yes
There can never be a galaxy without a black hole. The anti-matter is necessary to cause the matter to spiral. It creates a huge suction.
The Black Hole will explode because the gravity of a Black Hole is formed by the matter that is in the process of going intothe Black Hole, and not that matter that has already gone inside.
An active black hole is a black hole that it by all manner of terms is "feeding". That is, it is accreting matter, or sucking matter into itself. Most black holes are dormant and don't show any signs of accreting matter.
The material sucked in to a black hole becomes part of the black hole - that is, a black hole crushes matter to an nearly no size, at all.
Yes. A black hole will stop consuming matter if there is no matter nearby to consume.
Probably the mass of the black hole would increase, just as when normal matter falls in.
Within a black hole, the distinctions between regular matter and antimatter disappear.
Gravity. This a known and to some extent an arguably proven fact. But there are also theories that Black holes contain Anti-matter, an entity in inverse existence to "matter".

The rotation is not related to the black hole's ability to attract matter. The attraction depends only on the black hole's mass.The rotation is not related to the black hole's ability to attract matter.

All the matter that collapsed into the black hole, as well as any matter that fell into the black hole after the initial collapse. The only distinguishable part of such matter is its mass - any structures of matter, even atoms, get destroyed.

Any matter that enters the black hole will be destroyed. Also, it will increase the black hole's size.
You can't see the black hole but you can see its inflence on its environment. (You can see matter that is sucked into the black hole)
