More than one character on Skyrim

Just wondering, I'm about to buy it and it sounds awesome, but how many characters can I have in Skyrim on the PS3? Am I limited to just 1, or can I make more than one character at once?

If you're referring to how many character saves: As many as your harddrive has room for.

If you're referring to followers: Generally the rule stops at two. One follower, and one Dog (or Troll, depending on your DLC). However this is fairly fluid as there are quests in which you automatically gain a follower, and will stay with you to the mission end. And, just with almost every other part of the game, can be "Hacked" to gain additional permanent followers. (I stopped at a posse of 7).

This wiki page describes multiple followers more clearly if you are interested.
