A galaxy consisting of a few hundred billion stars is a mote of dust in the vastness of the universe. Our galaxy (the Milky Way) is about 100 000 light years across, the closest neighbor (Andromeda - she is very close in universal comparison to distant galaxies) is about 2 000 000 light years away. That means if you see light from Andromeda (which you can if you look in the right place on a very dark night) the light left Andromeda two million years ago (when there were not even any human beings on Earth yet)!
A scale model would have the Milky Way and Andromeda each the size of grapefruits (10 cm diameter) at a distance of 2 meters from each other.
There are about 300 000 000 000 (three hundred billion) galaxies in the visible universe, give or take a few. Most of the universe is not as densely packed as the group of galaxies that Andromeda and the Milky Way belong to, but is quite empty.
Last time i heard it, one small corner.
No, the growth of the universe is caused by the galaxies moving away from each other, with no relation to their size.
In relation to the Sun - roughly where we are now. In relation to the Galaxy 1/225 further around the Galactic core. In relation to the Universe. Who knows
Any such speed must be specified with relation to something: for example, with relation to the Andromeda Galaxy, the average of the Local Group, of the Local Supergroup, etc. There is no such thing as an "absolute speed".
the universe is bigger than the galaxy because our galaxy (the milky way) is in the universe.
Actually a galaxy is in a universe
A galaxy is a tine part of the universe.
The universe contains countless galaxies, think of the universe as a galaxy of galaxies.

galaxy is in the universe
a Galaxy is smaller because the universe holds everything
In the galaxy, we are in one of the spiral arms. We do not know where we are in the Universe.
