Stars and Galaxies are related because a galaxy is a system of billions of stars, gases, and dust.
See related questions.
Galaxies are generally a collection of stars. But within any galaxy, there are lots of other objects, including planets. So galaxies are related to planets in some ways.
That is related to their past history. Many galaxies have undergone collisions with other galaxies; this takes out most of the interstellar gas, and the galaxies can no longer form new stars. If I remember correctly, such galaxies will change into elliptical galaxies.That is related to their past history.

No stars are actually a galaxy. All stars are stars and all galaxies are galaxies. Stars are found in galaxies. Some galaxies look like tiny dots in our night sky, so might look like a star, but they are not stars; they are galaxies.
All stars and galaxies are in the universe.
A galaxy is a large system of stars, gas, dust, and dark matter held together by gravity. There are estimated to be billions of galaxies in the universe, each containing millions to trillions of stars. The exact number of galaxies and stars in the universe is still unknown due to the vastness of space and the limitations of current technology.
Yes, there are stars between galaxies. When there are collisions or interactions between galaxies, stars can be ripped out of the galaxies. These stars will then wander into space between galaxies. Such stars have been observed with the Hubble Space Telescope. Taken from http://curious.astro.cornell.edu/question.php?number=384
Smaller galaxies do. Larger galaxies contain billions or even trillions of stars.
Galaxies are the massive collection of stars. Therefore galaxies could not have formed without stars.
Elliptical galaxies may vary in shape form but are spherical or flattened disk-shaped galaxies (large groups of stars). See related link for a pictorial.
Bigger galaxies. And stars.
Galaxies ARE groups of stars. Lots of stars though. Not just like 2 or 3...
