Galaxies can be classified into three main sizes: dwarf galaxies, which are small and contain less than a few billion stars; Milky Way-sized galaxies, which are intermediate in size and contain a few hundred billion stars; and giant galaxies, which are massive and can contain trillions of stars.
That is a difficult question to fully answer as types of galaxies are not fully defined. A ball park figure would be dwarf galaxies, or spiral galaxies depending on the area in question. See related question for a full breakdown.
Nebulas are found in all types of galaxies, including spiral galaxies like the Milky Way, elliptical galaxies, and irregular galaxies. They are regions of dense dust and gas where new stars are formed. The variety of shapes and sizes of nebulas contribute to the diversity of galaxies in the universe.
It doesn't really work that way. The types aren't exactly related to size, but rather to shapes. Dwarf galaxies of course are the smallest; but other than that, a spiral galaxy can come in different sizes; so can an irregular galaxy or an elliptical galaxy.
There are generally three types of galaxies: spiral galaxies, elliptical galaxies, and irregular galaxies. Spiral galaxies like the Milky Way have a disk shape with arms of stars spiraling out from a central core. Elliptical galaxies are shaped like ellipses and contain mostly older stars. Irregular galaxies have a less defined shape and tend to have a mix of young and old stars.
Your question can not be answered exactly as it is asked. Many of the things in the universe come in various sizes. There are Galaxies and there are Super Galaxies. Super Galaxies can be bigger than clusters of galaxies. Planets and Moons come in all kinds of sizes. Some moons are the size of some minor and/or regular planets... such as Ganymede, and Titan for example. Both are larger than Mercury, and the minor planet Pluto. Pulsars are the remnants of a dying star, stars, meteors, and every thing you have asked about come in various sizes as well. I would recommend that you find and watch "The Universe" which I believe is on the Discovery Channel. There is an episode that deals with the largest things in the Universe. According to that source... the largest thing in the Universe is the "Cosmic Web". This show will deal with pretty much everything you have on your list. It is a very interesting show, and it repeats regularly.
Yes. All 100 billion galaxies come in all shapes, sizes, and colors.
It is possible that astronomers will measure all the sizes of 100 billion galaxies in the observable universe.
Yes. All ~100 billion galaxies in the universe come in all shapes, sizes, and colors.
Galaxy sizes range from smallest to largest in the following order: dwarf galaxies, spiral galaxies (such as the Milky Way), elliptical galaxies, and finally, giant elliptical galaxies. It is important to note that this is a general categorization and there is variation in sizes within each galaxy type.
Three galaxies would be the Milky Way, Andromeda, and Comet Galaxy.
Our own galaxy, the Milky Way consists of about 200 billion stars.

spiral galaxies (ours), irregular galaxies, and elliptical galaxies.
All galaxies are different sizes and mainly four different shapes,spiral,barred spiral,elliptical and irregular
Elliptical galaxies come in all forms and sizes. It impossible to answer.
No. They come in different sizes and different shapes, and have other differences as well.
