A white dwarf is very small as stars go; comparable in size to a small planet such as Earth.

No a white dwarf is a small compact star.
A white dwarf is typically about the size of Earth, but with a mass comparable to that of the Sun. This means it is extremely dense, packing a lot of mass into a small volume.
A white dwarf consists of the core of the large star it once was.
No. A dwarf star is a small star. A white dwarf is just one particular type of dwarf star, but there are other types.

That depends what you mean with "survive". A white dwarf can be considered dead, it no longer produces energy. But it will continue emitting light for trillions of years; it has a lot of stored energy, and a small surface area to radiate it.That depends what you mean with "survive".

The same size as the white dwarf it was. See related question.
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.
See related question.
White dwarf stars are not luminous because of their small sizes, they are not able to radiate a lot of light at once.
It is the Post-Main sequence star that burns helium. They are considered giants, unlike our sun, which is a Yellow Dwarf. they are extremely hot and large.
