Question

How many people can fit in st. peters square?

Answer 1

Maybe a couple hundred thousand or so if they are standing.

Answer 2

The Piazza is about 25,000 square meters (about 6 acres), so allowing 4-5 people per square meter (a pretty thick crowd) would result in around 100-125,000 people.

Note that on very popular occasions (declaration of new Saints, coronations and funerals of Popes) the crowd spills over to via della Conciliazione and neighboring streets, so that even more people might be present.

Answer 3

A LOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO...

Answer 4

Tens of thousands.

Unless, of course, they are Americans, in which case their bellies would bring the number down to about 300.  After all, we are the fattest nation on Earth.
