No. Assuming the sun's mass were compressed into a black hole, the sun would still have the same mass. The gravitational pull created by that mass would not be affected beyond the distance of the sun's present surface area.
A planet that falls into a black hole would get completely destroyed. Its mass would be added to the mass of the black hole.
I don't think there would be planets, but I know there are stars!
no
There are no known planets in the vicinity of a black hole.
A black hole
Such a black hole is never found, but theoretically it should be possible. If the planets are far enough from the black hole where they circle around they will just orbit the black hole in the same way as they would orbit a star with the same mass if it would replace the black hole. But if it exists it would be very hard to detect, exoplanets are detected because of their interaction with their mother star(They block some light and have gravitational influence that can be detectable), for black holes that is not an option because they are obviously black. The planets themselves won't emit light so there is no way we can detect such a system if it exists.
there is nothing inside a black hole...a black hole's density is very large...so large all of our planets and stars including the sun's density would not even be 0.1% that of a black hole...a black hole is so strong, not even light can escape it...nothing can.

They are unrelated.
I seriously doubt that. the planets would have to be very very close together. The black hole would have to be a super massive one as apposed to a stellar one.
you would float around till you get in a black hole or a planets grational pull
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.
