A supernova can cause either a neutron star or a black hole. (Black holes are caused by big stars suck as a red supergiant or a blue supergiant) :)
No. That is when stars run out of hydrogen. They then have helium for fuel.
When a Star runs out of fuel, it will expand into what is known as a "Red Giant". Massive stars will become "Red Supergiants". This phase will last until the star exhausts its remaining fuel. At this point, the pressure of the nuclear reaction is not strong enough to equalize the force of gravity and the star will collapse. Go to related link to read more about Stars... ;)
Stars that have ejected a planetary nebula eventually become white dwarfs. These are core remnants of low to medium mass stars that have exhausted their nuclear fuel. White dwarfs gradually cool down over billions of years to become black dwarfs.
The primary fuel for all stars is hydrogen
The two types of stars that do not fall into the main sequence of an H-R diagram are white dwarfs and giant stars. White dwarfs are small, hot stars that have exhausted their nuclear fuel, while giant stars are large, luminous stars that have evolved off the main sequence due to changes in their internal structure.
As with everything, stars age as well, and reach the end of their time. As stars age, they become different types of stars, based on how big they are, and how hot they are burning. When they run out of fuel, they eventually die.

Stars expand in size to become red giants, when they start running low on Hydrogen fuel.

Neutron stars could form in places where there are high-mass stars. After the star runs out of fuel in its core, the core collapses while the shell explodes into the space as supernova. The core would then become a neutron star, it might also become a black hole if it is massive enough.
What actually happens to the types of stars is that the low mass will turn into a white dwarf and the medium mass will turn into a black dwarf and reproduce a nebula
Yes, dying stars can become very bright. As they run out of nuclear fuel, some stars expand into red giants or supergiants, which can increase their brightness. Additionally, some dying stars, like supernovae, can produce intense bursts of light as they explode.
After a star like our Sun runs out of nuclear fuel, it will shed its outer layers and become a white dwarf. White dwarfs are created from low to medium mass stars (like the Sun) that have exhausted their nuclear fuel and undergone certain stages of stellar evolution.
