That is far too big a topic to cover in one thread. I suggest you look the words up in a dictionary, and then try to compose some sentences containing them. Post them here, and we can tell you if they are correct; we can also add a few suggestions.

As 5jj said, this is far too big a topic. However, in the meantime, please note the amendments I made to your post. Please review your use of capital letters and punctuation (especially the fact that you need to put a space after a comma).
