Yes.
The smallest galaxies may contain just a few million stars.
Large galaxies like our own, the Milky Way, contain between 200 and 400 billion stars.
The largest galaxies are Ellipticals, and may contain as many as 50 trillion stars.
That depends what you count as an "object", but I would say the answer is "no". Galaxies group into galaxy clusters, these group into superclusters, and then there are "walls" of galaxies. For an even larger structure, see this:

Yes. A celestial body is a general term for anything above the atmosphere that can be studied.

No. A galaxy is BILLIONS of celestial bodies - stars, planets, moons, asteroids - held together by gravity.
No, a constellation is not a galaxy. A galaxy is an enormous group of stars that are connected by gravity. A constellation is a pattern in stars that appear to an observer on the earth to be near each other. Essentially, human beings played "connect the dots" with the stars as they appear to us on earth, but the fact that two stars appear close in our night sky does not mean that they are actually close to each other in outer space.
A galaxy is a fundamental component of assembly in the universe which is a self-gravitating system consisting of ordinary atomic matter in the form of stars and the interstellar medium as well as dark matter. Galaxies rotate about a common gravitational center. Galaxies come in many shapes and sizes. The most common shapes are elliptical, spiral, and irregular. Our Galaxy, informally called the Milky Way, is a barred spiral. Many galaxies are believed to contain super-massive black holes at their centers. Stellar-mass black holes caused by supernovae are also found in galaxies.

Yes it is. In some cases a huge collection
You could say so, but they do tend to cluster. However, by our everyday standards, even within clusters, the galaxies are vast distances apart.
A galaxy is a group of stars and planets. Our solar system is one star group in the Milky Way galaxy.
A collective noun for a group of stars is a cluster of stars (small group) and a galaxy of stars (large group).
A large grouping of stars in space is commonly referred to as the galaxy. This can also be called the solar system since planets are also types of stars.
Galaxy
A large star is almost any star compared to us. There is no definition for a large or huge star for exactly that reason. Taking the relative dimensions from the smallest to the largest star, then our Sun would probably fit that category.
A group of stars, dust and gases held together by gravity IS CALLED GALAXY
A collective noun for a group of stars is a cluster of stars (small group) and a galaxy of stars (large group).
If the group is large enough, "galaxy" or "dwarf galaxy."
a galaxy
A large grouping of stars in space is commonly referred to as the galaxy. This can also be called the solar system since planets are also types of stars.
A galaxy is by a definition a group of stars. If there were no stars it could not be a galaxy.
The noun 'galaxy' is a singular, common, concrete noun; a word for an extremely large group of stars and planets; a large group of impressive people or things. The noun 'galaxy' is used as a collective noun for a galaxy of stars (heavenly luminescence or human luminaries).
galaxy are group of billions of stars
Galaxies contain stars and nebulae, as well as a large variety of other phenomena.
The Milky Way Galaxy
A galaxy!
That can be a large globular cluster, or a galaxy. Or any larger structure that includes galaxies.
