Sirius A does not have enough mass to become a supernova. It will end it's life as a white dwarf.
A red giant can become a supernova.
No, our sun is not destined to become a supernova and/or a black hole. It will become a red giant, but it is not massive enough to cross the threshold and become a candidate for a fate like either of those last two.
A supernova
If sufficient mass remains after the supernova explosion, it will become a black hole.
Nova (plural novae) means "new" in Latin, The prefix "super-" distinguishes supernova from ordinary nova.
No. It's a white dwarf, meaning that it has no more fuel left for such things.
The supernova would be so much brighter that it's hard to compare, at least 10 magnitudes brighter then Sirius. It would probably be about the same brightness as the full moon in the sky.
A red giant can become a supernova.
Sirius's fate might be peaceful; just ejecting it's outer red giant layers to make a planetary nebula. It is 2.02 times the mass of the Sun. However, Sirius has a white dwarf companion. On Sirius B's death, Sirius A might have formed. At the other end, Sirius B might destroy Sirius A. White dwarfs have very strong gravity, and if it is close enough, Sirius B might steal material from Sirius A. When a white dwarf stealing mass from the parent star has enough mass to create iron, the iron triggers a Type 1a supernova. If this happens to Sirius B, Sirius A could either be destroyed by the immense force of the explosion, or become a runaway star, travelling faster than even Barnard's Star. If this is the case, Sirius A might eat smaller stars or crash and burn into a larger star. If it heads towards us if this happens, we would be doomed.
Only a very, very few stars have mass enough to become supernova. Jupiter is a planet not a star. It is far to small to become a star, let alone a supernova.

A supernova
No. there is only 1 ghost.
If sufficient mass remains after the supernova explosion, it will become a black hole.
Oops! Not all stars end up as a supernova. To become a Type 2 supernova, the star has to be between 8 and 50 times larger than the Sun.
No. It does not have enough mass to become a supernova.
