If you have girlfriend and if she sleeps with another guy is that cheating?

If she is expressing feelings for another (especially sex), then yes that is cheating. To have somebody else "on the side", that is DEFINITELY cheating. It does not matter if it is involvement or Marriage.
Depends. If you are in a committed relationship, I would consider it cheating. If your relationship is casual, then either you or her can fuck anybody you choose.

Response to update: In what culture do you live? Most of us expect fidelity before the actual date of the wedding? And. . . if she doesn't WANT to be faithful to you know, if she doesn't want to be a loyal companion, why do you keep walking down the road with her like you're actually going somewhere?
That isn't a girl friend you are describing. She's a friends with benefits if there is no romantic feelings or committment.
That is the textbook example of what cheating is. It's cheating on you, whether you are married or not.
