white dwarf star
Yes, far smaller. A red dwarf is a whole star in and of itself. A white dwarf is the collapsed remnant of the core of a low-to medium mass star. A white dwarf may be about the size of Earth.
Such a white dwarf could not exist. Above 1.4 solar masses a white dwarf will collapse to form a neutron star.
No, the sun will eventually evolve into a red giant before shedding its outer layers and becoming a white dwarf. The white dwarf stage marks the end of its evolution, where it will slowly cool down over billions of years.
A white dwarf consists of the core of the large star it once was.
The same size as the white dwarf it was. See related question.
A white dwarf is very small as stars go; comparable in size to a small planet such as Earth.

no
No, it is not a dwarf star. It's fairly large as stars go, but nowhere near the largest. However, because it is both fairly large and fairly close, Sirius is one of the brighter stars in our sky.
After a large star like vv cephie there is a white dwarf.

A white dwarf could not become a red dwarf. A white dwarf is a remnant of a dead star. A red dwarf is a star with a very low mass.
A white dwarf is denser than a planet. White dwarfs are stellar remnants that have collapsed under gravity, packing a large amount of mass into a small volume. Planets, on the other hand, have much lower densities compared to white dwarfs due to their composition and structure.
No in the life cycle of a star, a white dwarf can cool and become a black dwarf
