can someone please help  me out

Most of your questions are simple definitions.  There's no "hint" or "help" we can give you, to help you learn, to see where you need more help, to help you figure it out for yourself, etc. -- the way this board is supposed to work.  You've either read this in your text, online, or even a standard dictionary, and remembered it, or you haven't.

Some of your answers seem contradictory, so some are bound to be incorrect. Compare Part 1, question 1 and Part 2, question 7, or Part 1, question 2, and Part 2, questions 3 and 8.
