Conjurer (You)
Anomen (Cleric)
Keldorn (Paladin)
Minsc (Ranger)
Jan (Thief)
As 6th character you have some alternatives
Jaheira: (I don't like her but people say that insect plague is great, after all she's a fine fighter and druid can be helpful also you can have a romance with her but I don't like her attitude)
Aerie: She got low HP, low level but great quantity of spells and her romance! Ah I love her!
Mazzy: If you need a sniper.
If your main character is a Figher/Paladin/Ranger so take Nalia (great mage) instead of Minsc or Keldorn.
My party is me (Fighter), Minsc, Anomen, Aerie,Nalia and Jan. It's a very funny party

You got another 2 choices yet you're powerful enough. Dark side is stronger
