Astarion as an elf should be proficient with Longbow, Light Crossbow and Shortbow but NOT Heavy Xbow UNLESS Astarion takes the Weapon master Feat at level 4.
Lae'zel should be able to use any weapon with proficiency but she would do best with Strength based 2 handed weapons like the 2handed sword, 2h axe, Maul, etc....
