They are correct. Excellent!

They are all grammatically correct but would sound less awkward if you made these little changes: 1) How much are you paid for the work? --> How much are you paid for your work? 2) Stop pleasing people they will be displeased with you whatever you do. --> Stop pleasing people; they will be displeased with you no matter what you do. 3) I dislike people. I feel uncomfortable when I am surrounded by people. --> I dislike people. I feel uncomfortable when I am surrounded by them. 4) The film is totally founded on facts. --> This film is very factual. Hopefully that helps!

Thank you Daniel

All are good. For the last sentence I would say: "based on facts" and for the first sentence I'd say: "...they will be displeased with you no matter what you do."
