You got the idea wrong. You can send these guests on quests just like the Felyne Cart. After completing two hunting quests, the guest hunters will be back. Then you can check if they succeeded the assigned quest or not and obtain some rewards. You can send up to 4 hunters in one quest. The more hunter there are and the better their equipment is, the higher chance they'll complete the quest.
