Hi!
The word "Bonjour" simply means "hello" in French. The word is most often used when greeting somebody you are not close with. When saying hello to a friend, family member, coworker, or somebody else you are familiar with, "salut" is an appropriate way to greet him/her.
I hope this helps you! Have a great day!
