I know about these documents but Currently we don’t use any of these, so want to understand it.
The approach I take in my training at http://learn.pmstudent.com is to demonstrate the creation of project artifacts from scratch, and explain them as I go. Templates are OK, but the problem is trying to learn from them. It is very difficult to really understand how to use them effectively unless you have created them yourself. Afterward, you can use other templates and adapt them as needed because you’ll understand them thoroughly.
You can certainly find examples by doing specific Google searches however. Just put a filetype identifier into the search.
For example the following query in Google will yield only .xls files for you:
Give a man a fish, you feed him for a day;
Teach a man to fish, you feed him for a lifetime.
