There are five people in my family. (NB You could correct this as, ‘My family has five people.’ However, this is not a natural way to say this.)  My elder brother and sister are married and my younger brother is studying at the university so none of us live (‘lives’ in formal British English, ‘live’ in less formal British and American English)  at home. However, we will meet every week for a dinner with my parents on Sunday. (7)
