Other galaxies are moving away because the universe is expanding, but we are not at the centre of the universe.
The universe contains countless galaxies, think of the universe as a galaxy of galaxies.

Perhaps you are confusing Universe with galaxy. Most galaxies have a black hole in their center. The Universe has no such thing as a center.
The galaxy, the one we are in, we call the Milky Way. It is one of billions of galaxies. These galaxies and everything else make up the universe. Compared to the universe galaxies are small fry.
All galaxies are massive clusters of stars scattered across the universe. Many galaxies take the same form, for instance, spiral and elliptical galaxies. Some galaxies also have a black hole in their center.
Like our galaxy contains billions of stars, the universe contains billions of galaxies.
universe is largest. universe is made up of billions of galaxies.
Several. 1) That our Earth is NOT the center of the Universe. 2) That our Sun is just one star amongst many in our galaxy. Muslim astronomers reached this conclusion long before Galileo, but he proved it to the Western World. 3) That our Sun is nowhere near the center of that galaxy. 4) That there are other galaxies in our Universe. 5) That these galaxies are not static with respect to each other. 6) That there are hundreds of trillions of other galaxies in our Universe.

Universe is describing the galaxies. There are different galaxies and our galaxy is called Milky Way Galaxy. There are some other galaxies miles away from ours.
The estimated number of galaxy mergers, given that there are 100 billion galaxies in the universe, is 100 billion.
There is no such thing as the "center of the Universe". It is believed that the Universe looks the same from different places, there is no way to determine a "center". The farthest observable galaxies move away from us, at several times the speed of light.
