Assigning a password in Word through makros

Tell me to write a few links to a macro, to each link your macro and each macro assign your password! The main thing is that it is one file... how to do it through word?
I have five references! I need them to be locked up. Each with its own password! And it's in one file!
You let me download my document and you need the number 2 link from the archive, I send you the password from this link, you do not see other links!
For those who don’t understand it in other words:
For example, the document Word is written five paragraphs. Each paragraph is assigned a password. When you enter a password, you only see the information for which the password was written. The rest of the information is in hiding mode, and so that this information cannot be viewed, you need to put an additional password for editing the document.
