Yes. We're currently orbiting a super-massive black hole located in the center of our galaxy.
Yes, a planet could orbit a black hole, just like it could orbit a star. Gravity would bind them together. A planet orbiting 93 million miles from the sun feels exactly the same as if it were orbiting 93 million miles away from a black hole with the same mass as the sun has.
By "within" a black hole, I would imagine you mean within the event horizon. Such an object won't ORBIT the black hole - it will simply fall towards the singularity.
They don't specifically orbit the black hole. Stars orbit the Milky Way because in general, they are attracted to the other masses in the Milky Way. The supermassive black hole is only a tiny fraction of the total mass of the Milky Way. Well, you might say that they move around the black hole, but that's only because it happens to be there. Without they black hole, they would move around the center of the Milky Way anyway.
By observing the movement of nearby objects. The gravity of the black hole will accelerate such an object according to Newton's Second Law (F=ma). More specifically, the details of the orbit of a star that moves around the black hole will vary, depending on the black hole's mass.
Define a "hyper black hole". A "Hyper Black Hole" is a massive "Black hole" thought to be created by many Black holes merging together. Theological Physics now believe that most galaxies, including our own Milky Way, have a "Hyper Black Hole" in the center
Absolutely, planets can indeed orbit a black hole, just like how they orbit a star. Black holes have a strong gravitational pull, which means anything that gets close enough can swirl around it just like happy little planets in a cosmic dance of creativity. Just imagine the beauty of these orbits, friend - it's like painting a lovely universe full of wonder! üååüñåÔ∏è
No, the sun does not orbit a black hole in the center of our galaxy. The sun orbits around the center of the Milky Way galaxy, where there is a supermassive black hole called Sagittarius A.

If the Earth magically became a black hole, the moon and other satellites in orbit around Earth, would be literally ripped apart into tiny bits and swallowed by the black hole.
Yes, The sun and the solar system orbit the center of the galaxy where there is a black hole.
Yes. Any collision of a black hole with another object would change its velocity and therefore its orbit. But massive black holes orbiting each other, especially if they are in a close orbit, will also lose orbital energy through gravitational waves, and therefore get closer and closer until they eventually collide.
How far you have to move to remain in orbit around a black hole, or to escape it, depends on the distance from the black hole, as well as the black hole's mass.

because the black holes that they think are at the center of galaxies most likely have rotation, and the stars around it orbit the black hole somewhat like an accretion disc.
All galaxies orbit around a central core - firmly believed to be a massive black hole.
A black hole can definitely get to the size of a planet. The width of the largest known supermassive black hole is thought to be over ten times the size of the entire orbit of Neptune around our Sun.
