A 1. Neutron stars form from stars with a stellar remnant of less than 5 but more than 2 solar masses
http://en.wikipedia.org/wiki/Neutron_star
You need a 20 solar mass star to form a black hole... the stellar remnant needs to be about 5 solar masses, that's what's left after the supernova

A 2. Hypernovae are the result of the explosion of Hypergiants... a star is designated a hypergiant if it is 100 solar masses or more.

A 3. An ordinary white dwarf would have 1.44 solar masses or less.
A 4. red dwarf is less than half a solar mass down to the mass of a brown dwarf which is about 0.075 solar masses.

A 5. Wolf-Rayet stars are 20 solar masses or more

They're a special situation of a collapse of a fast-rotating Wolf-Rayet star with a core greater than 30 solar masses that collapses to form a large, rotating black hole.

You could probably search each in less time it took you to type your question .... or if you're really desperate, open your textbook.
