Please bear in mind that a constellation (such as Perseus) is basically a direction in the sky. It really doesn't make much sense to talk about the distance from such a direction (which is a direction from our point of view), to some object. If you mean the asterism (the group of stars), the main stars of Perseus - or any other constellation - happen to be more or less in the same direction, but the distance from these stars to Earth vary quite a lot.
Not much. The nearest known black hole is at a distance of several thousand light-years.Not much. The nearest known black hole is at a distance of several thousand light-years.Not much.

It seems that the nearest known black hole is at a distance of about 3000 light-years.
Hardly any. The nearest known black hole is at a distance of about 3000 light-years; even if one of the nearest stars were actually a black hole, it wouldn't be particularly dangerous.
The supermassive black hole in the center of our Milky Way is at a distance of about 28,000 light-years. The nearest known stellar black hole is at a distance of about 3000 light-years.
The nearest known black hole is at a distance of about 6000 light-years, but it is quite possible that there are black holes closer to us.
The average travel distance from a black hole on Earth would depend on the distance to the nearest known black hole, which is typically thousands to millions of light years away. Traveling to a black hole would require advanced technology and is not currently feasible with our current understanding of physics.
There is not "a" black hole, but many of them. The nearest known black hole is at a distance of several thousand light-years, but it is likely that there are others closer by: only black holes that are very near of a partner (in a binary system) are easily found.There is not "a" black hole, but many of them.

None, really. At least, for us, and now. A black hole can be dangerous if it's very massive (such as a supermassive black hole). But mainly, a black hole would be completely harmless, unless it gets close - and the nearest known black hole is at a distance of about 3000 light-years. Even a supermassive black hole would be harmless at such a distance.
If by "explore" you mean to actually go there, near the black hole, that simply isn't possible with current technology. The nearest known black hole is at a distance of 3000 light-years.
The distance from a black hole to the sun can vary widely depending on the specific black hole and its location in the universe. Black holes can be hundreds to billions of light-years away from our solar system.
The nearest known black hole is at a distance of about 3000 light-years - so it is far away from the Solar System.
It isn't quite clear what you mean with "all these black holes"; the nearest known black hole is at a distance of 3000 light-years; the nearest known supermassive black hole is at a distance of 26,000 light-years. In other words, they are so far away that they aren't even mildly dangerous.
