Black holes would only suck in matter whose relative velocity is too low to escape the vicinity (escape velocity). At the event horizon the pull is so great and escape velocity is so large that it equals the speed of light and generally nothing can escape at that point. Even electromagnetic radiation emitted outside the event horizon but inside the black hole's photon sphere stands a good chance of getting sucked in, or more correctly, the curvature of space is such that directions that light would travel in would more likely intersect the event horizon the closer you get to it.
Black holes have such strong gravitational pull that they can theoretically pull in anything that gets too close, including people and rocket ships. However, the likelihood of a person or a rocket ship getting close enough to be pulled into a black hole is extremely low, as we are very far away from any known black holes.
You might think it would look amazing and scary! But... no. Black holes suck in light so it is not visible.
Astronomers think that the areas around black holes suck everything in like when a tub drains. But black holes are large amounts of matter that is packed into a small area.
White holes are theoretical regions of spacetime that expel matter and energy outward, the opposite of black holes which pull matter in. They do not suck up objects like black holes do. However, there is no observational evidence for the existence of white holes in the universe.
Unlikely. The universe is a very big place, even next to the largest black holes we know. For a black hole to suck in the entire Universe, it would need to be nearly as massive as the universe itself. There is no way that such a black hole could form.
They're still called black holes. A black hole remains defined as a black hole as long as it absorb everything near them, both energy and matter, including gas.
Absolutely anything and everything. They may even suck up time(!!!!!), but no one knows for sure.
Yes, even light. Nothing can escape them after passing the point of no return.
Everything can somehow provide energy, except for black holes, which only suck up energy.

Black holes. They can be so large that they can suck up universes at a time
The best answer to your question is that black holes are super massive. Massive objects have high gravitational pull which means that they will pull objects, including sunlight, into the black hole if something enters the black hole's event horizon.As opposed to common lore, black holes are not giant "vacuum cleaners" which roams around the universe destroying everything it comes near. Most galaxies are believed to harbor massive black holes and the stars in the galaxy are typically orbiting the the black holes instead of falling into them. In some cases, galaxies are disturbed(for example if two galaxies collide), and some solar systems may be pushed into the path of the black holes which will then "suck them in".
yes

Yes, all black holes 'suck stuff up'.
Black holes are basically highly compressed massive (has lots of mass) parts of space. The large amount of mass warps the space time around the black hole which causes intense gravity that suck everything in.
