1. The boss put me in charge of the project.
2. He [is stealing, steals] your work (from) under your nose! / No! I think I'm lucky (that) I didn't get fired.
3. They beat him under the nose(s) of his children. or They beat him under his children's nose(s). (I think both nose and noses are all right.).
4. You paint for yourself, but I paint for those who buy my paintings. There's more at stake than talent. [Would you please explain to me what is the meaning of "There's more at stake than talent"?] ("At stake" means something in danger of being lost; something that has been wagered and could be lost. In this sentence "talent" seems an unusual thing to lose. I think the artist means he may give up his own individual style of painting, but he will not lose a sale).
5. You are so nasty. That's no way to treat people!
6. First I took/mistook him for a professor. & First I thought he was a professor.
7. Would you please take/accept me as your pupil?
(I see no errors).
