The size of a galaxy means how old the galaxy really is and also the stars indicate how old the galaxy is. So both the size nd the amount of stars indicate how old the galaxy is.
Earth, Sun, Andromeda galaxy and then the universe. increasing size------------------------->
The only thing that can be directly observed is a galaxy's apparent size (angular size). Since galaxies come in different sizes, this can only give a rough idea of the galaxy's distance from Earth.
The sun is larger and brighter than about 95% of the stars in the galaxy.
I think it is very difficult to define size to a galaxy, as there is not real cut off point. Recent observations showed a "halo" of Stars around the Galaxy - a bit like suburbs to a city. Putting the size to 500,000 light years across. Current thoughts are that it is twice the size of our own Galaxy, so around 200,000 light years across. Maybe someone else can contribute a more recent guesstimate.
Our solar system is tiny compared to the size of the galaxy. If we take the outer edge of the solar system to be the outer part of the Oort cloud, then it is about 2 light years in diameter. By comparison our galaxy is about 100,000 light years across. The size ratio is similar to that between a grain of sand and a football field.
The nearest large galaxy to the Milky Way is the Andromeda Galaxy. It is of similar size and is visible in dark skies.
My answer is short and reliable;" NO "

It is not regular to have same size the android phone may have different size.E.g Galaxy Pop is slimmer than Galaxy Y.

A 2.0 Galaxy gearbox will fit a 2.8 Galaxy. The two petrol engines have the same size and specs, and are therefore interchangeable.Ê
It means the galaxy that is called "Milky Way". We are inside this galaxy.

Every galaxy contains stars, if that's what you mean. "Galaxy" means "big bunch of stars". No stars ===> no galaxy.
