No, it is a red dwarf
It is a black dwarf
It loses its outer layers because it has expanded to the point where gravity can no longer hold it together. The inner part of the star becomes a white dwarf, called a white dwarf because it is still glowing with the remaining heat of the dead star. It eventually becomes a black dwarf, where it has radiated all its energy out and no longer glows.
black dwarf or neutron star
After the sun runs out of fuel is will become a white dwarf, a neutron star, or a black hole.
A white dwarf is the remnant of a star that has already run out of fuel.
It is a black dwarf
Yes. It is a black dwarf.
A red dwarf star.
No, you cannot. As the name suggests, a "black" dwarf is "black" because it has stopped burning hydrogen/helium for fuel, and is now not producing energy and has cooled to the point that it no longer glows.
There is no fuel for a white dwarf. A white dwarf is a remnant of a star in which fusion has stopped. There is, however, quite a bit of leftover heat, so the white dwarf still glows.

A star, after using all of it's fuel explodes. We call this a super nova, and after this the star will either become a black dwarf star (or maybe a white dwarf) or it will collapse in on its self creating a black hole.
black dwarf or neutron star
No. A brown dwarf is a star that has too low a mass to start nuclear fusion. A black dwarf is a former white dwarf, the remnant of a low to medium mass star that ran out of fuel in its core.
After the sun runs out of fuel is will become a white dwarf, a neutron star, or a black hole.
It is dead. It becomes a black dwarf, just a rock.
A white dwarf star is a star that has burned off all of its helium and hydrogen fuel, but which is still hot. After it cools off (which would theoretically take hundreds of billions of years), it would become a black dwarf.
