When a star uses up all of it's fuel one of two things can happen: either it explodes as a supernova, releasing large amounts of gas and dust into the surrounding space; or the star will expand into a red giant (which will happen to our sun) and release it's outer layers gradually in the process. Both of these processes will produce a nebula.
The two main factors that cause a nebula to develop into a star are gravity and heat. Gravity pulls the gas and dust in the nebula together, causing it to collapse under its own gravity. As the collapse continues, the temperature and pressure in the core of the collapsing nebula increase, eventually reaching a point where nuclear fusion ignites, and a star is born.
Yes, a nebula is far larger than a neutron star. A neutron star is a few miles across. A nebula is light years across.
The Sun is a star, specifically a G-type main-sequence star, which is the star at the center of our solar system. It is not a planet or a nebula.

Yes, nebula are responsible for star formation, so ultimately that's exactly what they do.
Nebula
a nebula is cloud of particles which forms into a star.

A nebula may condense and ignite to become a star, conversely a star may explode and form a nebula.
A White Dwarf Star remains.
A Nebula is a gas of dust and minerals that surrounds a star. Also, a nebula is a birthplace of a star, where a star and sometimes a solar system is formed after a huge explosions
A star like our sun will shed a planetary nebula after its 'death'
No, a neutron star can't become a nebula. A neutron star is not made of atomic matter, has less mass than a nebula, and has no mechanism by which to expand.
No, Arcturus is a red giant star, not a nebula.
