Stars form in space when giant gas clouds start to clump together and collapse in upon themselves. This clumping is often caused by energy waves from nearby exploding supernova (dying stars). As they collapse, the molecules that form the clouds compress in upon each other to form helium and hydrogen. Once gravity pushes them together strongly enough, nuclear fission will begin to occur in the core of the star. This process will continue throughout the life of the star, until all of the fuel is used up.

It has been estimated that as many as 85% of all stars in our galaxy are "white dwarf" stars. Up to 97% of all stars will likely end up as white dwarfs.Correction: About 90% of the stars in space are actually Main Sequence stars.
No. Space is largely a vacuum.
In more space.
yes because they levitate in space gravity does hold stars up
The largest stars end their lives as black holes. These are regions in space with incredibly strong gravitational forces that can trap even light.
Meteors are made up of rocks and ice and dust from space where as shooting stars are falling stars.
Yes, iron is present in stars. Iron is formed in the cores of stars through nuclear fusion processes and is an important element in the life cycle of stars. When a star reaches the end of its life and goes supernova, iron is released into space, where it can be recycled into new stars and planets.
Because stars make up galaxies. Though not all of them help make up solar systems. But if there are no stars, then a galaxy becomes a bunch of empty space.

The most massive stars become black holes.
Less massive stars end up as white dwarfs. More massive stars end up as a supernova or a neutron star or for the really massive stars...as a black hole. As a star ends its time in the main sequence it either becomes a Red Giant and end its life as a White Dwarf or becomes a White Super Giant and ends its life in an explosion (supernova) and if it's really dense it becomes a neutron star or a black hole as mentioned above.
