No
No. Dwarf planets orbit stars just like planets do. Stars orbit the center of their galaxy. An object orbiting a planet would be a moon.
Planets orbit stars, stars orbit a galaxy. Planets are not "on" anything. A lot of stars out there have planets - we are just finding out how many now that we have better techniques to find them. So probably all galaxies have at least some stars with planets.
We can't even see individual STARS in other galaxies, much less PLANETS. We have no idea how many stars are there.
Uranus is in our galaxy, the Milky Way. Everything you can see in the sky at night without a telescope, all the planets and stars are all in our galaxy.
in the world, there are zero galaxies, so the answer is grains of sand. if your actual question was about the number of galaxies in the universe: there are more galaxies in 1% of 1/10 of the visible sky than on all the beaches of all the worlds oceans
We expect the Andromeda galaxy to be just like our own Milky Way galaxy. We can see stars (suns) in the Andromeda Galaxy and just as stars have planets orbiting them in our galaxy, we believe that there must be planets also orbiting stars in the Andromeda galaxy.

Stars do not have rings. Planets have rings.
A huge mass of stars and planets is called a galaxy.

The galaxy is not a planet. The galaxy is MADE of millions and millions of stars and planets.

Dust. Gas. Stars and Planets
No one knows. Astronomers are scanning the visible stars of our own Milky Way galaxy for planets orbiting faraway stars, but such planets would have to be nearly the size of Jupiter to be detected at such distances
