Formal:
* Здравствуйте, Джеймс! (Zdravstvuyte, Dzhejms!) - This is the most formal way to greet someone, and is appropriate for someone you don't know well or in a professional setting.
Informal:
* Привет, Джеймс! (Privet, Dzhejms!) - This is a more casual greeting, suitable for friends and acquaintances.
* Здравствуй, Джеймс! (Zdravstvuy, Dzhejms!) - This is slightly less formal than "здравствуйте" and can be used with people you know well.
Using the name alone:
* Джеймс! (Dzhejms!) - This is a very informal greeting and should only be used with close friends.
Note:
* "Джеймс" (Dzhejms) is the Russian pronunciation of the name James.
* The stress in all of these greetings falls on the first syllable of "здравствуйте/здравствуй/привет".
The best way to choose the appropriate greeting is to consider your relationship with James and the situation.
