They are personal questions
Je ne connais pas mon ami.
I'm not sure because I've never read the poem before, but just some tips:
1. think about why the author wrote this poem
2. What do you think about it
3. Read it over and over until you can understand what the author is saying perfectly
4. Ask an adult to help you understand the poem if you're having trouble
