Ok this is kind of two questions
can anyone tell me how many know galaxies are out there, and some of there names. The ones i know are the milkyway (duh!) and andromeda
There are literally billions of known galaxies. Most of them have rather uninteresting designations. But there are a few that have ‘common names’ such as the Whirlpool galaxy, the Blackeye galaxy, the Sombrero galaxy, the Antenae galaxies, Stephen’s quartet, etc. More have ‘Messier’ designations (Messier was a comet hunter and catalogued a number of ‘fuzzy’ objects). Another desgination for the Andromeda spiral is M31 for Messier 31. The Whirlpool is M51. Several of the Virgo cluster of galaxies are in the Messier list. After that, many of the nearer galaxies have NGC designations (from the catalog name); for example NGC 6561 is a nice spiral. Farther out, the galaxies tend to be specified by their place in the sky.

There are about 100 billion galaxies, but sorry I don’t know all their names!!

There are hundreds if not thousands of galaxies in the catalog. Most are just numbered, some are named (such as the Sombrero Galaxy for example). The primary viewable’s are the "Messier" objects, denoted with an "M" like M17 or M39 you also have the NGC and the IC as well.
Here is a link to many catalogs There are MANY different types of galaxies, from spiral’s to globular clusters. Check’em out!

The estimated number of galaxies is in the order of billions.
Here’s a list of galaxies:

Our Local Group of galaxies is one of the smaller groups, and it has about three dozen known galaxies. The three largest in descending order are Andromeda, ours, and M33. Ours has two satellite galaxies, the Large and Small Magellanic Clouds. Andromeda also has two, M110 being one. The others in our group have names like Leo I and Leo II.
Since billions of galaxies have been found, no one is trying to name them all. A few, like the Black Eye Galaxy and the Whirlpool Galaxy (a/k/a M51) got names, but most have catalog numbers. The early catalog (after M for Messier) was NGC for New General Catalog, followed by IC for Index Catalog.
Galaxies come in several types. The three big ones in our Local Group are all spirals. M.110 is an elliptical, which is the most common type. The Magellanics are both Irregulars. A type not found in our group is the Barred Spiral, and also the Giant Elliptical, which can have as many as a trillion stars.
The Virgo Cluster of galaxies has at least 4000 galaxies in it, and larger clusters are known.

Well, as someone has said, there are billions, and some do have names that have been given (usually due to an unusual shape or brightness)
The ones that come to mind most readily are the Blackeye (so named because if the large cloud of dust which obscures part of its nucleus), the Whirlpool (because it is seen face on and is the best example of a spiral galaxy) the Sombrero (obviously because it looks like one), the Ring Galaxy (which appears as a simple ring, the result of a galactic collision many billions of years ago) and of course the Magellanic clouds that are in the southern hemisphere (both are irregular galaxies). Add these to your own list and you have a good start. Perhaps someone will add a few more?

Part of your question can’t be answered ,,,, A solar system is made up of planets a galaxy is made up of solar systems,,,,, Untold numbers of galaxies make up the universe ,,,,the universe is believe to be infinite ,,,, As far as I know ,,,, other than our own galaxy the Milky Way and the one next to us ,,,, The Andromeda Nebula little else is really know ,,,, Man has his hands full just studying our own galaxy and the Andromeda Nebula as it is ,,,,,

well,i can’t tell u how many galaxies are out there coz,the universe is expanding and more galaxies are formed this very minute.but i can assure u there are lots,LOTS of galaxies out there.do u know the Hubble telescope?if u don’t,it’s a telescope created by Edwin Hubble.this telescope helped us to look far beyond our galaxy,like the Horsehead nebula and many more.the furthest pic that hubble can get is called ‘Hubble Deep Field’.u can look it up in the internet if u want to.
the galaxies i know other than milky way is the Tadpole, Cartwheel, Spider, Antennae, Barbon, Barnard, Bears Paw, Black Eye, Carina Dwarf, Circinus, Draco Dwarf,Helix, Lost, Pancake,Pegasus Dwarf,Pinwheel, Sunflower, Small Magellanic Cloud, Ursa Minor,and Silver Coin. There are many more out there,believe me.

The total number of observable galaxies is estimated to be around 100 billion, based on what was seen in the various Hubble deep field images.
The largest catalog of galaxies is the SDSS (Sloan Digital Sky Survey) catalog, the first installment of which lists 200 million objects, most of them galaxies. They have also taken spectra of 675,000 galaxies.
As for named galaxies, another list is at http://www.iitk.ac.in/ac/right/util/naga.htm . It’s got some that aren’t on the Wikipedia list, though it’s also missing some from that list.

if you go to http://www.shatters.net/celestia/
you can get a free astronomy program.
once you have installed that, go to:
http://www.lepp.cornell.edu/~seb/celestia/galaxies.zip
there you will find a file that will show you 1,825 cataloged galaxies.
so far we have only cataloged 131.601 galaxies, even though there are millions of millions.
