The Sun is a medium mass star on the main sequence.
white dwarf. unless you count black dwarf of which none have been observed, only theorized.
White dwarf stage. Its shrinks to a lot extent in this stage. Edit: A high mass star is usually one that becomes a supergiant then a supernova. Eventually this should leave either a neutron star or a black hole, depending on the mass of the star. The previous answer is for low mass stars.
The Sun is a medium mass star in main sequence.
The maximum mass of a star is the mass at which it would collapse to form a black hole, irregardless of the stage in its life cycle. It is thought that the centers of the galaxies did this.
Protostar!

There is no general name. How a star ends depends on its mass.
Its mass and its stage of life
The maximum mass of a star is the mass at which it would collapse to form a black hole, irregardless of the stage in its life cycle. It is thought that the centers of the galaxies did this.
Protostar!
it doesn't.......
In some binary systems, the less-massive star has become a giant, while the more-massive star is still on the main sequence. If higher-mass stars evolve faster than lower-mass stars, how do the lower-mass stars in such binaries manage to leave the main sequence first? This is called the Algol paradox, after the binary system Algol.
It's mass and it's stage of life.
Formation of the star out of a giant cloud of gas and dust.
A protostar is the first building block of the main star. As it has not yet accumulated enough mass to join the main sequence, it will be smaller than the main star. The next stage will be a T Tauri star.
