A star that has undergone expansion, deflation and cooling is known as a white dwarf, or degenerate dwarf. It is a small star made up of mainly electron-degenerate matter.
A cooled white dwarf is a black dwarf. I think you are thinking of a neutron star which has nothing to do with a white dwarf.
The general category is known as a dead star. There are three kinds of dead stars: 1. a white dwarf, which oddly enough by its description does not seem to be a dead star - "a dim very hot star" 2. a neutron star (viewed as a typical pulsar close to a normal star, but emitting x-rays); or 3. A black hole. The smallest and least dense stars become white dwarfs and the biggest, densest stars become black holes.
A black dwarf does not burn anything. A black dwarf is the cooled remnant of a dead star.
Aldebaran, also known as Alpha Tauri, is classified as a type K5III orange giant star. It is the brightest star in the constellation Taurus and is easily visible in the night sky. As an orange giant, Aldebaran is in a later stage of its stellar evolution, having expanded and cooled after exhausting its core hydrogen fuel. This has caused it to swell in size and change color from its original main sequence phase as a type A star. Viral Faces AI - Unlimited AI Face Video Creator
Yes
Such a star is called a red giant.
A black hole is a collapsed star that does not let light escape. A nebula is a mass of gas and dust that may collapse to form a star. A red giant is a star that has expanded and cooled. A white dwarf is an old, dense, cool star.

No. A black hole can be a very condensed star. It's also possible for "mini" black holes of less than stellar mass to exist. But in no case would it be possible to describe one as an "expanded" star.

6, and then there was an animated expanded universe movie.
No. The sun is a main sequence star. A black dwarf is the remnant of a dead star that has cooled. The universe is not old enough for this to have happened yet.
Probably Star Wars, as you have the films, animated series, expanded universe books to factor in.

4 i think in the movies. In the expanded universe there are many more.
A star in a transitional phase where fusion is increasing causing an increase in the radiation pressure opposing gravitational contraction.
