The universe definitely has more than one black hole. Just in our galaxy alone there's an estimated 100 million of them, and the observable universe has at least 100 billion galaxies.
A black hole is more powerful than anything in the Universe except an XZ Majoris Ceiphei, so indeed you would have to die if you fell into a black hole for sure; except if you ARE an XZ Majoris Ceiphei.
It is believed that a black hole will slowly evaporate. But for a black hole that has the mass of a star, this will take much, much longer than the current age of the Universe.
That depends exactly how you interpret the term "strong". In its vicinity, the black hole distorts space more than anything that is NOT a black hole; so much that nothing can get out of the black hole. But at some standard distance, a galaxy, for example, would have more gravitational attraction than a black hole, simply because it has more mass. At least, so far no black hole of the mass of an entire galaxy has been found.That depends exactly how you interpret the term "strong".

I can't tell you the exact time, but it would probably be somewhat quick. The sun is made up litterally of flames and gas. All the black hole would have to do is pull the flames and gas into the mouth of the hole and the sun is gone. It seems to me that it would take a few minutes, depending on the size of the hole. If it is a small hole, made by a star about the size of our sun, it would take around three to five minutes. Maybe more.
I think white dwarfs. This is because they are much more low mass than black holes. White dwarfs are much more common in the universe than black holes, because we have only discovered a few black holes whereas we are aware of many white dwarfs.
Maby the universe
It is a possibility that the Universe resulted from a black hole, and that black holes in our own Universe result in new universes. But all this is extremely speculative.

It doesn't "need to live", but it will, whether it needs, or not. A black hole with the mass of our Sun or more is very resilient; it will continue existing - as a black hole - for much, much longer than the current age of the Universe.

Yes, larger bodies of dark matter that are considered responsible for pulling apart the universe.
Deeper than the aybess are any black hole in the universe.
they drink red bull
no there is not once you enter a black hole you are crushed but your matter can be possibly shot out as radiation but other than that no there is no other universe or dimension based on my research

A black hole of the mass of the Sun will take somewhere around 1067 years to evaporate. A supermassive black hole can take 10100 years or more to evaporate. If you write it out, this latter is a 1, followed by 100 zeros; in any case, much longer than the current age of the Universe.
A black hole has more mass than a neutron star, but if you are comparing volume it would depend on the mass of the black hole. A neutron star is estimated to be about 14 miles in diameter, which is larger than the event horizon of a black hole up to about 3.8 times the mass of the sun. A more massive black hole will be larger.
