Yes.
There are stars called "High-velocity" Stars.
They are able to escape the graviatational pull of a galaxy. They due this with the help of the super-massive black hole at the center of most, if not all galaxies.
Let's assume a binary star system gets close to the super-massive black hole. The black hole will literally steal one of the stars and the other will be zoomed out from the galatic center due to the energy exerted by the split. This gives the star enough velocity and strength to successfully exit a galaxy. Astronomers have found about 1000 of these stars.
Nifty.

yes. Rogue stars sometimes are flung outside their parent galaxy. Just today in the news, there was an article on a possible high mass star that went nova outside a galaxy. It was on msnbc in the science and space section.

Yes, they exist. No all that many of them but they are there. Generally they form in galaxies in the normal manner, but during galactic collisions gravitational stresses force them out of the galaxies. It must be lonely.
