A giant star is a dying star that expanded, and the core shrinks are the same time. When the shell of the giant star drift into space as planetary nebula, the core became a white dwarf. The white dwarf is made from the core of the giant star.
A stars evolution. Our Sun will go yellow dwarf -> red giant -> white dwarf -> black dwarf.
Red giant - Black dwarf. See related questions.
there are 2 stars i only know that is the white dwarf and the red giant
when Dwarf Stars run out of hydrogen they form Red Giant stars, then from that they become White dwarf stars when the outer layers shed, forming a planetary nebula.when giant stars or supergiant stars run out of hydrogen they form red supergiant stars
stars are not always white there are many different types of star for example: Black Dwarf Red Giant White Dwarf Blue Giant Neutron they are all varying colors because of the configurations of gas and energy of particals. however 97% of our galaxy's stars are the fabled white dwarf these are white because they are expelling there entire energy at once, the white dwarf is the final stage of a stars life, aside from the purely theoretical black dwarf

No. Sirius consists of two stars. Sirius A is larger than the sun but is not a giant. Sirius B is a white dwarf,
Yes there are a few more [See related link for more information].--- Main sequence stars -----Red dwarf Yellow dwarfBlue dwarf (hypothetical)--- Degenerate stars --------White dwarf Black dwarf (hypothetical)--- Sub stellar stars -------Brown dwarf.
It depends on its size. Smaller stars- main-sequence, red giant, planetary nebula, white dwarf, black dwarf Bigger stars- main-squence, red giant, supernova, neutron star.
