Okay, I saw another question like this before. I cant write an essay for you. But I can give you pointers and tips.
Uh..it depends on what the topic of the essay is. If it has any form of torment included in the topic to that should be ok..if not, then I wouldn’t use it just to be safe..but ask your teacher to make sure it’s ok. I know some teachers are protective about that.
A proper noun is just a specific noun and starts with a capital letter. Some suggestions: Honda Civic. McDonald's. (Your name). Texas. Grand Theft Auto. The Hunger Games. (Your teacher). Time Magazine. Red. Despicable Me. I hope this helps :)
