I generally never just use someone’s name unless I’m absolutely positive the other person knows who I’m talking about. I would just say, “my friend Jack” to a new person. I’ve always found it odd when people use names but I don’t know that person or their relation to the one I’m talking with. I’m from the US, so I really think it just depends on the person.
