It is not currently known how a supermassive black hole forms, or how long it takes. However, since they are present in early galaxies, they must have formed soon after the galaxy (at the lastest), in a fairly short time. I would guess they took no more than a few hundred million years to form, perhaps even less.
The supernova stage itself lasts only a few days or weeks. Once the star runs out of fuel, the collapse into a neutron star or black hole (depending on the remaining mass) should be quite sudden - whatever it takes for matter to fall toward the center.
Basically there is no "next stage". Well, it is believed that a black hole will evaporate, but that will take a long, long time.
For all scientific reasons, no astronaut had went inside a black hole. It would take many earth years to visit the black hole, so reaching a black hole is impossible.
A black hole starts as a dying star. As the star gets smaller as it dies, the inner pressure becomes so powerful that the star implodes. When this happens, the smashed atoms of the dead star come together to form a neutron star. When this is crushed to nothing, a black hole is formed. If a black hole does not get enough energy, it will decrease in size and eventually explode.
It depends on how much mass the black hole had. If the black hole had the mass of our Sun, it would take a long time, around a hundred million years. For a really big black hole, with a hundred million times the mass of our Sun (as is thought to exist in the centers of some galaxies), it would take about ten thousand years. One thing to remember is that at such great distances the gravity of a black hole acts like the gravity of anything else with that mass (e.g., if the Sun were magically turned into a black hole with the Sun's mass, the Earth would orbit as it always does. We'd just get cold without the Sun's radiation!). The weird effects you read about for black holes happen only very close in.

The sun should not become a black hole. It does not have sufficient mass to undergo the necessary collapse.
Yes actually. But it well basically take billions of years for a hyper-novae star to explode and form. And supernovae do not form Black Holes, they make quasars or neutron stars. Hypernovae- a result of a hyper-class star to explode- will leave a black hole.
You get the shark to come near you and follow you to the black hole, then when you get to the black hole you turn a let the shark in. Have fun!
probably not long.My Answer:This is one of those questions that will depend on where you are observing from. If you are the one in a black hole and the most basic measure of time and death are used: Once you are in the Black hole your death would be instant.Traveling into the hole and dieing may take virtually forever because of the way a Black Hole distorts time and gravity.If you could figure out how to watch from out side no human could live long enough to see a person die and confirm that he/she was dead. Again this is due to distortion of time.
If you were to get too close to a black hole, it would take a very short amount of time for it to kill you due to its intense gravitational pull. The exact time would depend on the size of the black hole and how close you are to it, but it could be a matter of seconds to minutes before you are pulled in and crushed.

Yes! It is because time is relative, and so the process of getting sucked into a Black Hole will be long enough for you to live your life before your body begins to disintegrate. In fact, even right now you are in the process of getting sucked into a Black Hole at the center of our galaxy. But it will take millions and millions of years for you to reach the point where you enter the Hole. It purely depends on the intensity of the gravitational pull of the Black Hole. If it has infinite gravity, then it will take you infinite amount of time to reach it.
