Generally based on the relationship between male and female friends (not engaged), the woman's parents are called: uncles and aunts. If you say uncle, it seems that the woman's parents are older than her parents or older than her parents. Besides, calling uncle is more kind than calling uncle. The woman's grandparents still use the girl's name, and other relatives just use the girl's name. The girl's parents call her uncle and aunt, her brother calls her brother and her sister calls her sister. Other relatives just follow the girl.
