OpenGL doesn't deal in pixels, but in internal units which are completely arbitrary. The pixel size of any OpenGL object is going to depend on the projection and model/view matrix you use. Take it from me, you're not going to get far with OpenGL by asking a few random questions here. It's a BIG subject. I strongly suggest that you get yourself a good book on the subject, ideally in your native language. For references online, the classic is the OpenGL Red Book, http://www.glprogramming.com/red/. And don't forget that Android only implements the small OpenGL ES subset of the API; a reference for that is at http://www.khronos.org/opengles/sdk/1.1/docs/man/. Good luck!
