I believe the Naval Observatory Merged Astrometric Dataset (NOMAD) is the most complete star catalog to date, containing about 1.1 billion stars.

Will you believe if I say 6.375 x 10^11 stars? Kidding. Its not easy counting the number of stars in a galaxy. But yes, the Milky Way contains about 300-400 billion stars.

A few million. Mostly the distances are unknown, so we don't know exactly where in the galaxy they are. The Gaia spacecraft should improve the situation considerably.

A lot of those stars are red, faint, and far away and so they don't show up in any telescope images.
