Scientists estimate that our galaxy contains somwhere around 100 billion stars. They are also finding that planetary systems are more common than first thought. current estimations run about 1 star out of 1 million could potientally have a planet with life on it, which is roughly 100,000. Considering the millions of galaxies, I'd say it's a certainty that there is other life out there, it's just a question of when will we make first contact not if there is life on another planet.
You can't live on a star, I doubt any life form would be able to withstand 5,000F+ without being incinerated. A star is not a galaxy, a star is like our sun, stars are among the trillions in the universe.
