I believe
In terms of MASS, may be comparable to our sun.
In terms of Size/volume, may be comparable to planets.
A white dwarf is much larger than a neutron star.
A white dwarf could be smaller or bigger than the moon since it's size varies depending on the mass of the white dwarf. Since the mass of the moon is 7.347 x 1022 kg and the mass of Pluto is 1.31×1022 kg the size of a white dwarf is also smaller or bigger than Pluto depending on it's mass.
Jupiter is far larger than the other two. White dwarfs can be treated as Fermi gasses, and have the interesting property that as their mass increases their radius decreases. So the smallest is actually the 1.2 solar mass white dwarf.
Saturn, Uranus, and Neptune are all larger than Earth but smaller than Jupiter.
The obvious reason is that the specific star has bigger density compared with the Sun. For example, that star could be a "white dwarf star". A white dwarf mostly contains "electron degenerate matter", which is very dense. A white dwarf is a small dense star.
Yes.
YES. A typical white dwarf star is only a bit bigger than the Earth.
A white dwarf is much larger than a neutron star.
Yes. The white dwarf would be a bit bigger than the Earth.
Generally, they are not much bigger than the Earth.
Jupiter is bigger than earth

If you meant "Is Jupiter bigger than the SUN" then no. The sun is bigger than any planets in our known solar system.
the next stage of a white dwarf is the black dwarf which is form when the degenerate electron slowly cools down by thermal radiation but the time required for a white dwarf to become a black dwarf is bigger than the current age of universe so the evidence of a black dwarf isn't found yet

No
