If sufficient mass remains after the supernova explosion, it will become a black hole.

A massive star. Usually any star with more that 9 solar masses will explode as a supernova.
Following certain types of Supernova events there can often be a gravitational collapse of massive stars and this can result in the stellar remnant becoming a neutron star. Based on the Tolman-Oppenheimer-Volkoff limit the solar mass of a neutron star can range from 1.5 to 3.0 solar masses.
Supergiant stars of at least eight solar masses will explode as Type II supernovas.
Depending on the mass of the original star it will either end up as a neutron star (< 20 solar masses) or a black hole (> 20 solar masses).
If sufficient mass remains after the supernova explosion, it will become a black hole.

Stars with a mass about 9 solar masses, or greater, will explode as a type II supernova.
A lot of mass. Generally for a type II supernova more that 9 solar masses. See related question.
A massive star. Usually any star with more that 9 solar masses will explode as a supernova.
A supernova may have been a supergiant star at one time, but it did not have to be. Any star with a mass greater than 3 times our sun will supernova. There are millions of stars having masses between 3 solar masses and supergiant mass for every single supergiant star... and every one will supernova when it dies.
Supernova. Stars below nine solar masses become white dwarfs, though stars more than 1.4 solar masses (Chandrasekhar limit) should nova during their life time. http://en.wikipedia.org/wiki/Supernova http://en.wikipedia.org/wiki/Chandrasekhar_limit

Yes, eventually they all burn out. Stars with less than three solar masses will become a neutron star. These are extremely, extremely dense forms. Any larger and the star will become a black hole after going supernova.
The amount of mass in the remnant. If the mass of the remnant exceeds 3 solar masses then it will become a black hole.
Supergiant stars of at least eight solar masses will explode as Type II supernovas.
