I don’t know what you meant in the first sentence but I think I can make sense of it. 1: how old were you when I was 5 years old? 2: I liked to play with my friends when I was young. 3: who did you play with when you were in primary school? 4: where did you go with your friends when you were young? 5: you’re the funniest of your friends 6: my sister is 5 years old and she likes to read, what did you read when you were 5 years old?
** I am fluent if mexico spanish not spain so they may have different meaning of words but they shouldn’t be too different so these should be right.
