Nobody has any idea. Several hundred have been identified. But it's a hugely difficult process, and more keep being discovered all the time. It's beginning to look like most stars have planets, and nobody is even sure of how many STARS there are in the Milky Way Galaxy, because some of THEM are so hard to see..
The Milky Way galaxy is estimated to contain anywhere from 100 to 400 billion stars. Given that planets tend to form around stars, it can be inferred that the Milky Way likely hosts a comparable number of solar systems.
The Milky Way probably has billions of planets; only about a thousand are known so far.
The Milky Way does not have any moons. Moons typically orbit around planets, not galaxies.
