Astronomers do not know the answer to your question. But, in Andromeda, there are billions of billions of stars, meaning there must be billions of billions of billions of planets. The only reason why we can't detect them is because the light from the stars obscures the light from the planet. Basically it is invisibile to us. For example, if you turn on your car's headlights, put an ant on it, and moved back couple of feet, you would only see the light of the car's headlight not the ant. But, in our universe, we have detected many planets. One major project is California & Carnegie Planet Search a joint UC Berkeley and other colleges project. They have discovered 182 planets in nearby stars in our galaxy. You should check it out: http://exoplanets.org/

This is a hard question to answer being that they have onlt found a little over a hundred planets in the whole Universe. It is so tricky because they have to get light to bounce off the object that their trying to see. They haven't discovered nearly all the planets in the Andromeda galaxy, so giving a straight answer isn't possible.

Nobody is ever likely to truly KNOW, because there is no imaginable way in which this precise information could be gathered.
We can fairly confidently estimate that there will be about as many planets in that galaxy as there are in this one. On current estimates, that's at least a billion.

No, nobody does. We've only found 30-some in our own galaxy. There are surely billions of them here. We have absolutely no way at this point of seeing even one planet in another galaxy.

No. We've found more than 150 outside our own solar system, but we haven't looked at many other stars, and we can't easily detect planets right now, so no one knows. Easily billions though.
