Our planet earth and seven planet live in the milky way, and along with other stars above, and will you believe there is another milky way of other planets does exist?

Yes, there are billions of other galaxies like the Milky Way. The Milky Way alone has something like 200 billion stars. We are just beginning to be able to detect planets around nearby stars, but it looks like many stars have planets around them.
The nearest large galaxy is M31 in the constellation Andromeda. In a reasonably dark sky you can see it with the naked eye as a small hazy spot.
The Hubble telescope has taken several "deep field" photos, where it points at a tiny patch of starless sky for a long time. Each of these shots has shown thousands of galaxies.

Uhm. First, we should clarify some terminology
Here's the hierarchy of structures in the universe, from small to big (omitting some things that are not important to this question):
solar system, galaxy, galaxy cluster
Our planet, earth, is in a solar system. A solar system consists of a star and whatever stuff is orbiting around it - planets, asteroids, etc.
A galaxy is basically a very, very, very large grouping of stars all orbiting the same central point. It consists of stars, solar systems, gas clouds, and other stuff floating around.
Galaxy clusters are just what they sound like: groups of galaxies.
The milky way is a galaxy. The one we live in. Our solar system is inside the milky way galaxy, along with billions of other stars and/or solar systems.
The milky way is one of billions of other galaxies in the universe.
So...could there be life on another planet, in another solar system, perhaps in another galaxy? It's certainly possible. Myself, and many others, consider it to be almost certain that life exists elsewhere in universe, just because of the huge amount of stuff (and therefore the huge amount of opportunities that life has to arise) in the universe. Odds are, if it happened once on earth, it probably happened in at least...at very least...one other place too.

Milky Way is a name of the galaxy in which our solar system along with other stars exist. If milky way means any galaxy then of course there exist billions of galaxies in universe(s) containing planets.

I think that I do read some where that there is another milky way like ours. The latest report that I read say that our milky way had more planet we use to know.

If the photograph voltaic gadget have been kicked out of the galaxy for the period of a collision with andromeda, no longer something could happen to it incredibly (no longer something definitely touches in the time of the "collision"), and sure we would see a plenty darker evening sky in particular with out stars. yet perchance we would have a sturdy view of the milky way! The Earth does no longer be flung removed from the sunlight. The photograph voltaic gadget could be kicked out as an entire.

Milky way is the name given to the Galaxy that our solar system is in - and yes there are millions of such galaxies in this universe.
