Stars are expected to end up as white dwarves, neutron stars, or black holes. If you are interested in the stages before that (when the star still produces power), that include red giants, and supernovae.
It varies, depending on the stage of the star's development.
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.
On the contrary, "protostar" is the name of an early stage in the development of a star.
A Star spends most of its life on the "main sequence" of the Hertzsprung-Russell diagram (see related link below). While here it is called a "main sequence" star and its source of energy during this phase of its life is the fusion of hydrogen into helium in its core.
The death stage. It explodes and either collapses into a neutron star or collapses even more into a black hole in space.
The Neutron stage follows the White Dwarf stage of star development.

the fourth stage of a star is "supergiant" and its also the hottest stage
Protostar Stage
It doesn't differ from a star, it is a star and it is the second stage in a stars life after the nebula stage.
The first stage in a star's life is as a nebula. As the gravitational forces spin faster, the star enters it's second stage, that of a prostar.
It is a supergiant.(the late stage in the life cycle of a massive starin which the core heats up, heavy elements formedby fusion, and expands; it can eventually explodeto what scientist call a supernova.)-Missy K
Yes black hole is last stage of a star
yes, it is the stage where a star dies and turns into a blackhole
what is the third stage of the star cycle
