What is a normal and can somebody give me an example?

The vector perpendicular to and pointing away from the front of the object's plane.

See Wikipedia: Surface Normal
from which comes this image:

A second view point? I only have pictures from the birds eye view. There are different pictures with different lightings.

Any other ways you guys can think of?
