I think that's unlikely. The only relevant features of black holes are its mass, electric charge, and rotational momentum. What makes dark matter different to baryonic ("normal") matter is that it doesn't interact with normal matter, except through gravity - so it seems that none of the differences would be relevant, once such matter is converted to a black hole.
No. Without matter there would be no black hole. The black holes confirmed to exist so far actually have a fairly large amount of matter (or mass) - at least 2-3 times the mass of our Sun. The largest black holes have millions or even billions of times the mass of our Sun.No. Without matter there would be no black hole.

Black Holes' can 'eat' any type of matter in the Universe.
No, dark matter is quite a different kind of thing. A dark hole may have absorbed some dark matter, but pressumably that would become indistinguishable from the normal matter, once it gets crushed by the enormous gravity of the black hole.

White-holes are a theoretical hypothesis that they are the opposite of a black-hole, in which case they would push matter out into space yes.
One of the considerations for the eventual termination of the universe is that all matter will be pulled into black holes, and then these black holes would eventually evaporate.
there is no exact answer, different black holes have different speeds, but all black holes can crush 1 tonne of metal into a size of a pebble
Stars & black holes.
Bursts of light from black holes are the result of the accretion (or "consumption") of matter by black holes. Quasars are an example of this.
black holes swallow all energy and matter around them, including electricity
That's what the mathematical theories suggest would happen. We have never observed this, and with any luck we never will be close enough to see this. Black holes are dangerous places.
The black holes may not devour everything since the outward velocity of the matter in the universe may escapethe gravitational pull of the black holes. Stephen Hawkins reckons that even the mass in the black holes would diminish over time, though over trillions and trillions of years.
