Considering a neutron star is about the size of a city, a subgiant is way bigger.

Both. A subgiant can be a young star (1,000 years old) to an old star (10 billion years old). See related question.
A white dwarf is much larger than a neutron star.
A neutron star is about the size of a small city. About 12km across but with the mass of about 2 Suns.
No. A neutron star is quite small, generally only a few miles across. A nebula is light years across.

A binary star. The main component is a Be-type subgiant.
No galaxies is way biger than a star, a star is .0000765% of a galaxy.
A typical neutron star has a diameter of about 24km our Sun has a diameter of 1.392×106 km So our Sun is about 58,000 times bigger than a neutron star.
No. A neutron star is quite small, generally only a few miles across. A nebula is light years across.
No. While a neutron star has more mass than the sun, it is compressed into a very small area about the size of a city.
