Massive Stars.
Super nova supernuvae or supernovas are can be cause by reignition of nuclear fusion in a degenerate star or by the collaspe of the core of a massive star. Aging stars and white dwarf stars are the names of two super Nova starter kit.
A massive star [See Link] (one with a mass greater than 10 Suns) will experience a catastrophic event called a supernova. Depending on the original mass, the star may collapse and become a neutron star [See Link], or if the mass is great enough, turn into a black hole.
The most massive ones. The exact amount of mass requires varies, depending on the type of supernova, and on the element mix of the initial star.
A supernova is a star saying "The End". The H-R diagram shows they different types of stars by spectral class, color, etc. It was never intended to show the ending of stars. On most H-R diagrams, you will find at the top, or occasionally top right, a place for "Supergiants". Some of those stars will eventually become supernovas. To be absolutely clear: A supernova isn't a type of star - it is the "end" of a type of star.
The most massive stars will end up as black holes. Those are the stars that have more than approximately 3 solar masses at the end of their life - i.e., AFTER the supernova explosion.
Less massive stars end up as white dwarfs. More massive stars end up as a supernova or a neutron star or for the really massive stars...as a black hole. As a star ends its time in the main sequence it either becomes a Red Giant and end its life as a White Dwarf or becomes a White Super Giant and ends its life in an explosion (supernova) and if it's really dense it becomes a neutron star or a black hole as mentioned above.
They will end up as neutron stars or even black holes. Usually they will first explode as a supernova (of type1a).
Massive Stars.
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.
Heavy stars go supernova at the end of their lives.
No, but some stars can end their lives by becoming a black hole.

They are not. A supernova is an explosion of a star. Blue stars usually end their lives in such explosions.

many stars die as a supernova. not really able to determine which types, because they die at random, but if they dont die as supernovas, they just collapse and disappear into one point in the sky.
A supernova is not a single star, but an event that occurs to the most massive stars when they reach the end of their life. Therefore it cannot be named. See related questions for details on Supernova
