WordPress inherently is designed to be a single person blogging software. There are a few people working on getting a multi-blog thing going.
Please search for “multi blog” on this forum for some directions.

I think what Cypher meant was single “blog.” WordPress supports numerous users/authors, but just one blog per installation. Since you can have multiple authors, that’s not much of an issue. For posts, the correct author is displayed automatically. And you wouldn’t necessarily have to install yet another copy of WordPress; you could just pick one of the installations you already have.
Merging three blogs into one is where you’re going to hit problems. For posts, if you download the table to a sql dump (that is, export from the database to a text file), you could edit the post IDs in the INSERT lines, changing them all to NULL; importing them this way would cause MySQL to automatically assign a new, incremented ID (thereby avoiding duplicates). But then you’ll have no connection to categories, or meta data (custom fields), or authors. And let’s not forget comments!
What you want can be done, but it involves a lot of preparation and manual editing before you perform a merge of this sort. Even if there’s not a lot of posts in the various blogs, etc.
It might be better just to start a new “merged” blog, with links to the previous three from the sidebar. That way you are down to just one for all of you to use, but still have the previous posts available.
Thanks to everyone who replied. Now I feel really stoopid because I didn’t actually install WordPress, (my brother did) and I didn’t realize he had installed WP 3 times, once for each of us. Now that I realize that, I am aware of how stoopid my question must have looked. “How do I get my hammer to whack stuff??” I have now installed WordPress into the root directory of my development site http://www.fattriplets.com/devsite and I have some different questions, which I will post as new topics (After doing the appropriate research first).
