A supernova (plural: supernovae or supernovas) is a stellar explosion that creates an extremely luminous object.

No, Sirius will not become a supernova. It is a relatively young star compared to those that typically go supernova, and its mass is not sufficient to trigger such an explosive event. Sirius is expected to eventually evolve into a white dwarf.
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.
Highly unlikely in our lifetime. Altair is still on the main sequence and probably has a few billion years left on it. Even when it comes to the end of the main sequence, it may not have enough mass to become a supernova.
The onset of iron fusion causes a star to become a supernova. This process occurs when the star's core collapses due to the inability to support the fusion of iron, leading to a catastrophic explosion.
If the core of a supernova explosion contains three or more solar masses of matter, it will most likely become a black hole. The gravitational force is so strong that the core collapses into a singularity, forming a black hole.

No. It's a white dwarf, meaning that it has no more fuel left for such things.

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.
i dont know
It can either become a neutron star or a black hole. If the star is between 8 and 15 solar masses, it will become an incredibly dense neutron star. If it is more than 15 solar masses, it will collapse and become an even denser 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.

If it's a big enough explosion it will become a supernova
Because of the distances involved, a supernova could have occured today, but we wouldn't know about it for thousands or billions of years. As with all things in space, what we observe is what was, not what is.See related questions for last observed supernova.
Among other things, they will have less fuel available. Eventually, a star will become unstable and convert into a giant star, or even blow up as a supernova.
