Most of the time in KOTOR, you will not be alone. This is a party exploration game. Even when you first start, you will be accompanied by someone. The first main character you meet when you truly get through the first "orientation" level is Carth; a Republic soldier who believes loyalty is the greatest thing, yet he doesn't quite trust you yet. One of your mini-quests, should you want to do it, is to find out more about him. Again, I can't continue to stress how deep this game is. Even in the story, there are stories. Anyway, as you progress in the game you will meet more characters that will join you in your quests. You'll even meet Wookies, droids, members of the Jedi Council, and what I have figured is Yoda's ancestor. Carth and most of these other people will become available to take with you wherever you go. You can have 2 party members with you at any time. Combat is definately better when you have help. And each person has their own specialties, so at anytime, you can switch back and forth to control anyone in your party.
