I just bought the Civ 4 complete edition from Steam with the 3 DLC packs, and I now have 8 different versions in my library. Four of them are SteamOS versions, but I can't figure out what to do with the other 4 versions. Can I not play a game with all 4 versions enabled at once? How does this system work? Civ 3 and Civ 5 all have a single version, why not Civ 4?

As Jason mentions, four of the entries can be safely ignored, depending on your OS. Whichever ones won't install are the ones that won't run on your system.
The four remaining ones are:
Unless you hate the things Warlords and Beyond the Sword add, there's really no reason to play the "base game" Civ4.
Beyond the Sword incorporates almost everything in Warlords, minus a few scenarios. If you want the "full" Civ4 experience, you might as well play that one. I didn't like Beyond the Sword that much though, (I think it was the tweaks to the tech tree, or maybe Espionage?) so I tend to prefer playing Warlords.
Colonization is a totally separate game, so it has very little to do with Civ4 and its expansions.
There is no "DLC" in the Civ5 sense - during the Civ4 era, the game got expansions but no standalone DLC.
