Firstly our sun is too small to become a black hole. Only stars that are a million to a billion times our sun do this, because they burn through their fuel quickly, unlike our sun.
A typical black hole has 3 times the mass of our sun
It depends on how big the black hole is. If the black hole is small enough it will evaporate into nothingness before it could have any effect on the Sun. However if the black hole didn't evaporate, and if it fell into the Sun, the entire Sun would gradually fall into the black hole.
If the sun were to be sucked by a black hole, it would be ripped apart and stretched into a process known as spaghettification. As the sun gets closer to the black hole, the extreme gravitational forces would cause a strong tidal force that would stretch the sun into long, thin streams of matter. Ultimately, the mass and energy of the sun would be absorbed by the black hole.
It depends on how much mass the black hole had. If the black hole had the mass of our Sun, it would take a long time, around a hundred million years. For a really big black hole, with a hundred million times the mass of our Sun (as is thought to exist in the centers of some galaxies), it would take about ten thousand years. One thing to remember is that at such great distances the gravity of a black hole acts like the gravity of anything else with that mass (e.g., if the Sun were magically turned into a black hole with the Sun's mass, the Earth would orbit as it always does. We'd just get cold without the Sun's radiation!). The weird effects you read about for black holes happen only very close in.
The Schwarzschild radius is a theoretical radius a thing(here: Sun) would need to be compressed to to become a black hole.
In the course of normal stellar evolution, at end of its life the Sun wouldn't spontaneously become a black hole simply because it lacks sufficient mass. The minimum mass of a stellar black hole would be about 25 times that of our Sun; effects through which stars lose mass would also need to be considered.
YES
No. The Sun is a star - as you can see if you look out of the window.
It isn't big enough.
Simply put, it isn't big enough. A star must have a certain mass to become a black hole after its "death", and the Sun doesn't have enough. Our "Sun" is not big enough, only stars that are a lot bigger will explode and become a black hole.
we will not be able to know since the sun will grow as big to literally melt the earth.
10 to 20 times larger
If it gets close enough to the Sun, a black hole would swallow up most of the Sun - becoming a larger (more massive) black hole. A small part of the Sun's matter, i.e., part of its gases, would probably escape into space.

No. There not a black hole on the sun or on Jupiter.

Black Hole Sun was created in 1994-05.
