Planets are usually much smaller than stars, certainly for our solar system. For another solar systems you might find a very large planet and in others systems you might find a very small red dwarf star or a small dense neutron star that has come to the end of its life. Here, the large planet of one system might be larger than the star of another.
Presumably, the destroyed planet Krypton belonged to our own galaxy, the Milky Way.
No, Betelgeuse is not a dwarf planet. Betelgeuse is a supergiant star located in the constellation of Orion. It is one of the largest and most luminous stars known in our galaxy.
a galaxy is a collection of Stars and planets while a planet is simply a large mass of rock, in orbit round a star. If you wanted to be able to distinguish the two from each other by simply looking at them in the sky, this is impossible.
No, a planet does not necessarily have to rotate around a star. There are rogue planets that do not orbit any star and instead wander through space independently. These planets are not bound to a specific star and travel alone through the galaxy.
Most stars orbit around the center of a galaxy. Some stars are parts of star clusters; in that case, they will also orbit around the center of the star cluster.

A galaxy.
a) Earth is not a star, but a planet. b) Earth is not part of "another galaxy", but of our own galaxy.
A galaxy is larger by far.
Neither -- the Moon is technically a satellite. It is in orbit around a planet. That planet orbits around a star. That star is one of billions of other stars which form a galaxy.

Universe, Cluster, Galaxy, Star, Planet NB: Some stars are smaller than planets.
The order from largest to smallest is universe, galaxy, star, and planet. The universe encompasses everything, including galaxies like the Milky Way. Within galaxies, there are stars like our sun, and planets like Earth.
A galaxy is a cluster of stars and gasses and a planet is something that goes around a star. Can you see why this might not make sense?
Presumably, the destroyed planet Krypton belonged to our own galaxy, the Milky Way.
The order from largest to smallest would be: star, galaxy, planet, filament. Stars are individual astronomical objects, galaxies are collections of stars, planets are celestial bodies in orbit around stars, and filaments are structures in the cosmic web that connect galaxies.
