I think you are asking if we could stay alive in a black hole if we did not stay very long.  I would say no.  Some scientists do think that we will eventually be able to travel through time, or that it is theoretically possible.  All I can say is, I hope not.  If no, there would be people from the future amongst us now.

You wouldn't expand in a black hole, you would be crushed. I seem to remember reading somewhere that, in a blackhole, the Earth would be squashed down to the size of a beach ball because all the particles would be under so much pressure that all the space in between them would be squashed down and that's how much matter the Earth is made of!

Black holes are extremely bizarre. A black hole is not an object in the real universe, it is a rip in the fabric of reality. They are in some ways linked to 'The Big Bang' and it is hypothesised that our Universe could have been started by the creation of a black hole in another universe. But this is only an idea at the moment.

If it is possible to stay alive in a blackhole, it will need unimaginably advanced technology to survive the forces. And what happens when you step outside time? I have absolutely no idea.

That stretching effect takes place when you cross the 'event horizon'. The event horizon is not the black hole. The event horizon is the 'no turning back' point. Once you cross it you will be pulled deeper and deeper into the black hole's local region. The black hole is a miniscule singularity in the centre of that region.

While black holes are one of the most fascinating things in the universe, they are extremely difficult to observe and even the greatest minds disagree about their nature. To be honest, I only have a very vague concept of this subject.

Many of the questions that you have are best answered by saying, "we don't really know, but maybe it's this or maybe it's that." We have a lot more to learn about them before we can know for sure.

I do not understand #5's explanation. can you please brief it? 

  I think, black hole is just a strong gravitational force that attracts everything-even light.
