Andromeda is younger than the solar system, which has beat it by about 1.5bln
That is impossible. A universe, whether infinite or finite is still vastly bigger than a galaxy.
A galaxy cluster consists of several galaxy groups, each of which in turn contains several galaxies. So no; a galaxy cluster is MUCH bigger than any individual galaxy.
Yes.The only ones I know is IC 1101 and Messier 87.The Andromeda galaxy is twice the size of our Milky Way.The Andromeda is 260,000 light years across,while the Milky Way is 100,000 light years across.A light year is 5,878,499,812,499 miles.
The Andromeda Galaxy can be seen from the northern hemisphere. Above the 45th parallel it is circumpolar, meaning you can see it pretty much any time of the night. If you know where Cassiopeia is, the Andromeda Galaxy is a fuzzy patch of light visible to the naked eye (on really dark nights) between that asterism (the Flying W) and the constellation of Andromeda. The five bright stars that make up Cassiopeia--Andromeda is below the W. The rim stars are dim, even through a good 14" telescope you can generally only make out the core stars. Otherwise the galaxy would appear a bit larger than our own moon, from our perspective here on earth. Andromeda is 2.5 million light years away, and a bit bigger than our galaxy.

A galaxy is many many times larger than one sun.

M31 diameter is 220,000ly, Milky Way diameter is 258,000ly, according to newest observations, we are almost 2x more massive
Just about as far as the closest star in the Andromeda Galaxy. The diameter of the Andromeda galaxy is ... well, quite huge, but still relatively small, compared to the distance between us and the Andromeda Galaxy. And I believe this diameter may still be smaller than the uncertainty in the distance estimate!

No, the Milkey Way is the galaxy that Earth is in.
Our galaxy is called milky-way. It had different kinds of stars, planets and super no a. It had hundreds to billions of stars in here Andromeda is more bigger than our galaxy, milky-way. Scientist says that milky-way and Andromeda will collide and will formed milkdromeda.

Yes. The Andromeda Galaxy is estimated to contain about 1 trillion stars.
One can not realistically measure the size of a galaxy in terms of the size of the Earth. One usually measures the size of a galaxy in terms of light years. The solar system of which the Earth is just a small speck sits in our local galaxy, the Milky Way which is 100,000 to 120,000 light years across, while the Andromeda galaxy is slightly larger at 220,000 light years in diameter.
