ELI5: What is in the center of the galaxy?

Also what makes all the stars spiral around it. Also if are galaxy is a apart of a greater orbit of like a super galaxy or if thats possible?

More than likely a supermassive black hole.  This is what pretty much everything in the galaxy orbits around.  We cant see it directly but from our observations of other similar galaxies we can assume ours is pretty much the same.
Also our galaxy is part of a larger group of galaxies called a super cluster.  They dont orbit anything specifically but are held close together by their gravity.
