ENGLISH A.1.1- R

Greeting is a gesture of courtesy that shows the value of social gestures in interpersonal relationships. A gesture of acknowledgment towards another is the greeting. A greeting is shown through common formulas such as "Hello", "Good morning", "Good afternoon", "How are you?". Greeting is a brief contact in personal encounters.

If they are people close to you, with whom you have had a close relationship, such as friends and family, then you can greet informally. If, on the other hand, you are in a work, business or study situation, it will be more appropriate to greet them formally.
