1-3 are fine, but 4 and 5 aren't.

4. I have as many books as you have books.
5. I have as many books as you have them.

[I have written down possible sentences. Which ones are used? Did #1 come from #6?]

since "many" is vague and unspecified, #6 in no way implies #1. For example, #6 might be:
I have 100 books.
You have 1000 books.
We both have "many" books, but #1 is clearly false.
Still, in the context of these sentences, maybe #6 means #1, since we seem to be talking about equal amounts of books.
