Nebulae typically do not contain large stars, as they are usually formed by the explosion (ie, supernova) of a large star, and contain remnants of that star only...a neutron star, possibly a pulsar. However, W26 is a star in the southern sky in the constellation of Ara. This star is has a radius equal to 1500 times that of our sun. Its not a main sequence star, its a red supergiant, but a cloud of ionized hydrogen does surround it, and that qualifies as a nebula. W26 is the largest star known, so far as I am aware, but may very well not be the one with the most mass.
A nebula galaxy does not exist.
Trifid is a nebula, not a star. For a the largest star, see related question.
The largest star known to man is called the Pistol Star. It lies in the center of the Pistol Nebula in the Milky Way and is believed to be 100 times bigger than the sun.

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 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.
