You need to fight the monster listed. They'll usually pop up at a random spot on the world map or a certain location where they're usually found. Defeat them and one will randomly ask to join your party. You can boost your chances (I think) by using Luka's 'talk' function. This will improve affection and increase the chance of getting the girl to join you.
