Does the nikon e8800 have a 50mm lens?

My granddad gave me his and I was wondering what kinda of lens I can get it

It's a point & shoot bridge camera. They don't have interchangeable lenses.

That camera came out about 7 years ago, but you can still find some details and some reviews for it (just google the camera model).

I would strongly suggest you read a bit about that camera and about cameras/photography in general. You have much to learn, but that camera could be a great start until you're ready to upgrade some day.
