I need native speakers' help!!!

I’m writing my degree work. Could you help me? Could you answer several questions?
1) Do you think that “Good morning”/ “Good night” is a wish?
2) Do you often use the full structure of your wish? (I wish you…)
3) Do you think that the imprecation is the wish of the evil?
4) Which is the most popular wish to anyone in your opinion?

Thank you!!! I really need it!!!
