Alright I'll do 7-10. Here are my guesses:
7. My favourite dessert is a banana split - True (because everyone loves a good banana split)
8. I’ve beaten Minecraft 5 times before - True
9. I found Planet Minecraft on December 9th last year - False (I feel like this is a trick question since everyone can see the date as to when you've made your account. So, I believe you found PMC earlier than that, just that you didn't make an account at that point of time)
10. My favourite type of pizza is Hawaiian - True
