It is theorized that due to quantum-mechanical effects, a black hole is not quite fully black, and slowly emits its contents in what is called Hawking radiation. An EXTREMELY slow process except for the smallest black holes.  As for any other options "conceptually, if this or that could be carried out within it" but very unlikely to take place in practice and out of question in practice for a human , who would have been obliterated by his entry to begin with -- I don't know.

It all depends on your situation.
If you approach with enough angular momentum, all sorts of things are possible. You can orbit a Black Hole just like any other massive object.
You can use it as a Gravity assist to change the course of your spacecraft without the expenditure of energy.
In fact if you found a smaller black hole orbiting a larger one, if you approached it just right, you could get a simply humongous speed increase towards your next target again without expanding energy yourself.

But yes you can escape a black hole.
You can not escape from a black hole's event horizon.

Yes. Stay well away from it.
