the only one that can be seen by naked eyes is Andromeda in moderately dark sky, though such a sky is available only in smaller towns and isolated areas reasonably far from population centers and sources of light pollution. It appears quite small without a telescope because only the central part is bright enough to be visible, but the full angular diameter of the galaxy is seven times that of the full moon.
By telescopes you can see plenty of galaxies ..

With the naked eye, providing you have good vision and dark skies, you would be able to see the Andromeda Galaxy, M33 and perhaps M81. You can also see two dwarf galaxies to the Milky Way, the Large and Small Magallenic clouds.
The number of galaxies visible from Earth depends on a lot of things such as equipment, exposure times, and seeing conditions. There is no set number. CCD cameras used in astrophotography can collect light over a period of time to eventually form an image. The Hubble Deep Field image (though taken from Orbit) shows galaxies that are so faint that it took hundreds of hours for the camera to collect the light from them, sometimes only collecting one photon per minute.

That depends on your location and what type of telescope you are using. In order to see most galaxies, you need to be in a very dark location. A few galaxies can be seen with the naked eye from a dark place, like the Andromeda Galaxy. A good amateur telescope can easily see hundreds of galaxies from a dark location.

Many ,in most cases they are so far away u thine they are stars but when u look with a powerful telescope it is clear it is a galaxies

It depends on the telescope.
Andromeda can be seen with the naked eye though. It looks like a faint fuzzy "star" on a clear night.

Far to many to name them all.
There are about eight visable to the naked eye (just about) - the most well know being Andromeda.
A half-decent telescope will also resolve the Small Magellanic Cloud and the Large Magellenic Cloud.

many, many
the current research activities have enabled us to do so
of course, u cannot do so with the naked eyes. specialised equipments are avaiable.
and there are many more galaxies than we can imagine
