Nebula are clouds of interstellar hydrogen and other gasses that span light years. Some may be dozens or hundreds of light years across.
Galaxies were once referred to as nebula. These are vast collections of stars, often a hundred thousand light years in diameter (as is our own beloved Milky Way) or more.
It is hard to say because we don't have that kind of technology yet. in the future we might know. But there are many theories like the bubble theory witch suggests that there is actually a multi-verse witch suggests that there are many different universes all in different bubble's So know earthling knows
While there may be some overlap in sizes, generally a galaxy is larger than a globular cluster. Nebulas are smaller, and neutron stars are probably smaller than Manhattan, while massing more than the Sun.
The largest known nebula is Tarantula Nebula
The Orion Nebula which stretches 20 light years
A galaxy is much larger than a Nebula, so a cluster of galaxies is going to be even larger still.
20 to 30 million year

Triffid Nebula, Eagle Nebula, Cat's Eye nebula
Emission nebula glow and reflection nebula reflect the light form other stars

Nothing can be on a nebula. A nebula is gases and plasma. It is where stars are produced. So nothing is on the Dumbbell nebula. because the elephant sat on your mom. LOL
An absorption nebula is a dark nebula, which absorbs all incident radiation without reemission.
The Crab Nebula is a nebula.
Triffid Nebula, Eagle Nebula, Cat's Eye nebula
A solar nebula is related to the formation of our Solar System, any other nebula is just a nebula.
