Our galaxy has as many as 400 000 000 000 (four hundred billion) stars, of which at least half are red dwarf stars. However, the Milky Way is a relatively large galaxy. A more reasonable estimate for the size of an average galaxy might be on the order of about ten or twenty billion stars. Astronomers currently estimate about 70 000 000 000 000 (seventy trillion) galaxies in the Universe. This comes out to somewhere around 1 000 000 000 000 000 000 000 000 (one septillion) stars in the Universe.
Of course, this is a very, very large number. For example, if every man, woman and child in the world had thirty times as much money as Bill Gates, the number of pennies would be equivalent to the number of stars in the Universe. Similarly, if you could have a group of fast typists typing ever since the Big Bang, it would take about three hundred thousand of them to type as many characters as there are stars in the Universe.

There are 10 to the 22nd to 10 to the 24th stars in the Universe.

Our galaxy has somewhere between 200-400 billion stars. There are easily that many galaxies with a similar number each. Lots.

The number has been estimated to be around 10 to the twenty-third power.
