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.
Planets orbit stars.
It is less likely for stars in the halo of a galaxy to have planets compared to stars in the disk of the galaxy. This is because the halo contains older stars with fewer heavy elements necessary for planet formation. However, some planets could still exist around halo stars, but they would be rare.
Galaxies/nebulae are at the top of the tree; each one contains several billion stars. Each star might have many planets orbiting around it, and planets can have many moons.
That would be a galaxy. Our solar system is part of the Milky Way galaxy, which contains billions of stars, planets, and other celestial objects.
A galaxy contains planets and a star system contains only stars.

On the contrary! A star has planets, which circulate it. And planets have moons. Stars do not circle planets.

Planets and stars have gravity.
Yes. There have been hundreds of planets discovered in other stars in the Milky Way. It has been estimated that the Milky Way likely contains hundreds of billions of planets.
A galaxy is a part of space that contains the planets stars dust comets asteroids and other particles.
The Solar System Makes the planets and the Stars.
