Karlach, Halsin and Minsc are good aligned. Shadowheart, Wyll, Jaheira (I guess) and Gale are agreeable enough to work with any party. Astarion, Lae'zel can work with evil/neutralish party. Minthara is perfect for an evil run.
Classes: divine casters: druids (Jaheira & Halsin), clerics (SH); arcane casters: Gale and Wyll, potentially Astarion as a trickster, skill classes: Astarion; fighter classes: Minsc (ranger), Karlach (barb) & Lae'zel (fighter)
