The total number of planets in the universe is unknown, but there are likely many billions, perhaps many with conditions similar to Earth.

More than 300 planets outside our solar system have been discovered. All are within our own Milky Way galaxy, because accurate observations of planet-sized masses in other galaxies is not currently possible. Theoretical extrapolations suggest that there are indeed planets around many stars in other galaxies as well.

Relatively 2.5 billion. Remember, The Milky Way is still a big place, so these mathematical calculations seem reliable. However, if you want to find out how many cryovolcanoes have been scientifically documented, then you're looking at what could be 1.5 to 2.34 billion.

There are over 100 billion galaxies (100 billion+ stars per galaxy) in the universe.

The universe is bigger than a galaxy. If we reword the question to read "How many galaxies are in the universe?", the answer would be hundreds of billions.
