Astronomers searching for additional planets beyond Neptune had reserved the name "Xena" for the "warrior princess" of the 1990's TV show. When they discovered a planet larger than Pluto, they assigned that as a provisional name.
After the IAU demoted Pluto from "planet" to "dwarf planet", the object tentatively named "Xena" received a permanent name of "Eris".
Eris is believed to have one moon.
Xena, considered to be the 10th planet, was named after a character in the TV series Xena: Warrior Princess. As of 2014, only 1 moon is known to orbit the planet, and was named Gabrielle after Xena's faithful sidekick.
No
Yes it is called Dysnomia.
Pluto ... which I think was the first member of the newly-defined "dwarf planet" category ... has two known moons.
Ceres does not have any moons or natural satellites. As far as we know at present, Ceres does not have any moons. Ceres, the smallest dwarf planet, has no known moons. However there are other dwarf planets with moons that we know of such as Pluto and its moon Charon.
Planet Sedna does not have any rings and as of current scientific observations, it does not have any known moons either. Sedna is a small, icy dwarf planet located in the outer reaches of our solar system, beyond the orbit of Neptune.
Yes, the dwarf planet Eris is named after the Greek goddess of strife and discord. It was previously known as Xena..visitMethodInsn
The dwarf planet Eris was known as Xena by the team that discovered it's existence. This name was used informally by the team and the media. An official name would have to have a name from creation mythology according to IAU standards. The name "Persephone" has also been considered (it would have been fitting next to Pluto) but it is already the name of an asteroid.
Venus and Mercury are the only planets in the Solar System that do Not have any moons. Even Pluto, a dwarf planet, has a moon.

Yes, for example Pluto is a dwarf planet and it has three moons. Eris also has a moon.Yes of the 5 named dwarf planets :-Pluto has 3 called Charon its largest then Nix and HydraEris has 1 called DysnomiaHaumea has 2 called Hi`ika and NamakaOnly MakeMake and Ceres have no moons
