They are simply known as LMC and SMC.
As far as what they are made of, They are simply galaxies.
hope this helped.
thought it probobly didn't
There are two satellite galaxies, the Greater Magellanic Cloud and the Lesser Magellanic Cloud, which orbit the Milky Way.
Canis Major Dwarf and Small Magellanic Cloud are irregular satellite galaxies of the Milky Way.The two irregular galaxies that orbit the Milky Way are the Large and Small Magellanic Clouds.
The Milky Way and the Andromeda Galaxy are the two giants in our local group. These two galaxies will collide, but neither one can be said to orbit the other. In some instances smaller galaxies might "orbit" a giant cluster, with periods measured in billions of years. Galaxies in general do not orbit anything. Instead they are all simply spreading further and further apart as the universe expands.
The Earth, along with the Sun and all the other planets orbit around the centre of the Milky Way Galaxy.
The Magellanic clouds are two small galaxies visible in the night sky only from the Southern Hemisphere. Up until 1994 when an even closer one was discovered, they were the closest galaxies to our own galaxy, the Milky Way. The Magellanic clouds are believed to be in orbit around our galaxy.
The Large Magellanic Cloud (LMC) is a satellite galaxy of our own Milky Way. It and the Small Magellanic Cloud (SMC) are visible from the southern hemisphere, and were named in honor of Ferdinand Magellan, whose crew sailing around the world were the first Europeans to see them.
What do you mean with "the" barred spiral galaxy? There is not one such galaxy; there are millions of them. Also, the only galaxies that can be said to "orbit" the Milky Way are some nearby dwarf galaxies. The galaxies in the Local Group (the group which includes the Milky Way) are gravitationally bound to the Local Group, but they don't exactly orbit one another; it's probably more like they orbit around their common center of mass.
I believe the current understanding is that galaxies (that are not part of local groups of galaxies) don't orbit anything. There is no universal center, matter seems to be distributed more or less evenly no matter what part of the sky we observe, and the galaxies are moving away from one another according to the current established principles. Some galaxies are members of groups of galaxies, and perhaps some of these groups are slowly turning on an axis, a little bit like materials in an accretion disk.

Gravity causes all orbits. It is believed that there is a "super massive" black hole at the center of the Milky Way, and most or all other galaxies, that serves as the primary source of gravity.
Yes, gravity exists in outer space. Gravity holds the moon in its orbit around the earth. It holds the earth in orbit around the sun. It holds the milky way galaxy together. It holds the local group of galaxies together. And the local group of galaxies might be a group of a string of galaxies held together by the great attractor.
Viewed from the Galactic North Pole, the Milky Way galaxy is moving anticlockwise.
