Surprsingly, yes. There are planets besides the 9 (well, now 8 because pluto isn't good enough to be a plante) planets in our solar system.

As of January 2007, 209 extrasolar planets had been discovered, most by indirect observation. The vast majority of those discovered were gas giants, orbiting much closer to their parent star than those in our Solar System.

They are discovered by indirect observations. Large gas planets (like Jupiter) effect the parent star's orbit because the of Newton's Third Law (for every action there is an equal and opposite reaction).

However, we will not be finding planet that are rocky like earth, mars, etc. This is because they are too small to see with a telescope. Also, they have too little gravity to effect the parent star's orbit.

Yes, without a doubt their are planets in every galaxy. In fact, some theorize that almost all suns have planets. We can detect planets that are large enough to cause a wobble in a star but smaller "earth size" planets would not be detectable by current astonomical methods. That's just in this galaxy. We cannot, nor is it likely, that we will ever detect a planet from another Galaxy, unless they are home to a civilization advanced enough to send us a message.

Probably, since it appears from current observations in our galaxy that planet formation is rather common.
But since the nearest galaxy Andromeda (if you don't count the Lesser and Greater Magellanic Clouds, which are small satellite galaxies of our own) is over 2 million light years away and we can barely resolve separate stars there, much less planets.
But its only a matter of time and technology before we find planets in other galaxies as well.

So far 4 have been discovered. And the better our technology, the more planets we will discover.
According to the numbers, there are literally billions of planets out there.

In my opinion, the universe is rather like our galaxy: it is one in a million others. So, yes (in my humble and amateur opinion) there are many many other planets out there, though none we can actually detect.

I would hope that there is lots inside as well as out .So yes I think there could be many ,Billions and billions as Carl Sagan would say

Almost definitely, but we can barely detect them a few light-years away, much less 4 million light-years away.
