Because they expand, due to modecules in the air, most red gaints start out as tiny stars known as "white dwarfs" which, over millions of years, expand to form a red giant. Eventually after billions of years the Red Giant collapses and turns into a supernova, which can then form into a Black hole
I hope this Answered your question! =)
Some of the SUPER GIANT stars are Sirius,Sun,Rigel,Betelgeuse,and procyon.
Some do, some become "bright giants" instead.
Smaller stars like our own expand into a red giant and then eventually collapse into a white dwarf, the more larger stars like a bright giant star expand into a hyper giant or a super giant. Super giant stars can go supernova and collapse into a neutron star, a white dwarf, or a black hole. The hyper giant stars go hypernova and make a gamma ray that eventually ends into a black hole.
Not all protostars become true stars. Some protostars may not have enough mass to sustain nuclear fusion in their cores and never become true stars, instead becoming failed stars known as brown dwarfs.
Shooting stars are not stars. They are bits of dirt and dust that burn up in our atmosphere, briefly making them look like stars. Most of that is debris is from comets or others bits of dirt in space, but they are not stars and were not stars. So stars do not become shooting stars.
Some examples of supergiant stars are Rigel, Deneb and Betelgeuse.

Rigel, Deneb, Delta Cephei, Betelgeuse, Antares.
Actually if a star is medium or low mass is will run out of fuel and turn into a red giant, once the stars atmosphere slowly drifts away and the core is remaining it will eventually become a white dwarf For more massive stars it will turn in to a super giant the will cause a supernova, after the supernova the star can either a black hole or a neutron star
The sun is a star itself. The sun is actually a very small star. There are stars that are WAY bigger then the sun.Like the VY Canis majoris star. The sun is invisible compared to that super giant star.
I suggest you do some reading on both, to get an idea what a neutron star really is, and what a supergiant is. For a start, some differences are: their diameter; their density; the fact that a neutron star no longer produces any energy.
There are many giant stars. Some of the most well known are:AlcyoneThubanOctantisAurigaeCapellaArcturusMira
A Giant is a star up to 10 times larger than our SunA Super giant is a star 10 times larger than our SunA white dwarf is a stellar remnant about 100 times smaller than our Sun.
Some metals become a super conductor when you freeze them
Because they are closer or actually brighter.
I can't understand this question. There are lots of these stars that are clearly visible. Some of the brightest stars in the sky are these types.
