quasar
There is no special name for that, since basically most galaxies have giant black holes in their center.
Let me clarify one thing... Basically, ALL galaxies, or almost all of them, have a giant black hole at their center. (If any galaxy does NOT have such a supermasive black hole, then it is likely that it had one in the past, and that it was ejected out of the galaxy.)

yes, there is actually a giant black hole in the center of our galaxy, but don't worry because we are safely orbiting around it. A black hole is basically really really really dense material, which forms a blob where the gravitational pull is so stong nothing can escape it, not even light. It can also bend the laws of physics
To understand the 'how' of the presence of a supermassive black hole believed to be in the center of the Milky Way, one would need to know of the mechanism of its origin, which is tied to the origin of the galaxy itself. If sufficient matter is present in a given location, gravitational forces cause the matter to 'clump' and if sufficiently strong, it will continue to accrete and gain in mass; above a certain mass, given favorable conditions, a black hole will form. This is believed to have happened during the formation of our galaxy. In the case of the black hole at the galactic center, calculations indicate it has managed to acquire over four million solar masses.
Our solar system is located inside the Milky Way galaxy about midway between the galaxy's edge and its center.our solar system is in one of the spiral arms of our galaxy. This is where most healthy young stars are, as opposed to the aging red giants nearer to the dense core of the Milky Way Galaxy. Nothing is particularly special about our position in space, besides the fact that it is an area of new star formation.if you want a picture then see the related link.
It's not "galaxy stars", but galaxies, that have the black holes at their center.All, or most, galaxies have a giant black hole at their center.
In the center of every galaxy there is a giant black hole.
Yes, incuding a giant one at the center.

At the centre of our Galaxy, the Milky Way
The rotation of the Milky Way is the result of the gravitational pull of a giant (supermassive) black hole at its center. Use the links below for more information.
No, it does not appear to have a giant cross. It is called a "Black" hole because it absorbs all the light that hits the horizon, reflecting nothing.
There are lots of giants in our galaxy. Betelgeuse is very big (about 20 of our Suns). The massive object / system (expected to be a supermassive black hole) at the center of the Milky Way has the mass about 2.6 million of our Suns.
