Sizes vary, of course. A typical size is a few hundred billion (10^11) stars; some of the larger ones can have more than 10^12 stars.
Our galaxy is a barred spiral galaxy and it has somewhere between 200 and 400 billion stars. Andromeda is an even bigger spiral galaxy.
I could not say how many stars the smallest spiral galaxy would have, or how many the largest. There are cases where two spiral galaxies are colliding.

∙ 10y agoThere is a huge range of ages. Some are billions of years old, others are just a few million years old, or even less.
A better question would be to ask how old the galaxy itself is.

∙ 12y agoDoing research some time I came to the conclusion that Irregular galaxies house Population I stars although an irregular galaxy can be formed after a collision with another galaxy, so it all depends on the situation.
Correct me if I am wrong.

∙ 11y agoAges of stars in any galaxy are a function of the star's place on the Russel-hertzsprung diagram and whether the stars are located closer or farther away from the galactic center. Some galaxies are so far away that the light from them takes 1000 to 1000,000's of years to reach our telescopes so at best those galaxies that formed on the edge of the explosion of the Big Bang are probably older than stars in galaxies which formed farther from the edge.
In side a galaxy, those near the center are older than those farther from the center. But, you can have a stray star away from the center perhaps being older than those located near the center of the galaxy. At best you can put an upper and lower limit on probably ages in stars in younger or older galaxies and probably have to use ball park guesses good enough for government work.
Ages from around a million years to the those suggested by the HR diagram depending on the mass of the star.

What is the Collective noun for an irregular luminous band of stars?
An irregular luminous band of stars is called a galaxyof stars.
Is a young galaxy an irregular galaxy?
That is unrelated to age. An irregular galaxy is one that has been distored by the gravity of nearby galaxies.
Which type of galaxy is composed mostly of young stars?
The spiral galaxy's.
Contains dust gas and young stars?
irregular galaxy
What type of galaxy holds the oldest stars in the universe?
Typically irregular galaxies have the oldest stars
How old are the stars irregular stars?
The same age as stars in other galaxies.
Why do irregular galaxies have no shape?
An irregular galaxy is a galaxy that doesn't have a specific shape like a pinwheel or an elliptical galaxy.
Why is an irregular galaxy called a irregular galaxy?
The same stellar materials and dust any other galaxy is made of - it just hasn't taken on a coherent shape - yet, or possibly it had a collision encounter with another galaxy, leaving it "irregular" - either is possible.
What contains dust and gas and young stars?
Hydrogen (and a little Helium).
What do you call stars grouped together?
Depending on size, that's probably either a globular star cluster (a vaguely spherical grouping of tens of thousands of stars within a galaxy), or a galaxy (an elliptical, disc-shaped or irregular grouping of billions of stars - including several globular clusters).
What is found in an irregular galaxy?
a irregular Galaxy is not normal
Is the sun a irregular galaxy?
Yes. A peculiar galaxy is a type of irregular galaxy.
