Different orphanages use different terms for their staff. If it is a Catholic orphanage you would address each nun by their name and rank (Like Mother Superior) or simply Sister (Maria). They are not recognized by their job duties. If it is a secular orphanage there will be many titles for the staff. The administrator or receptionist at that orphanage can tell you what all the staff are called. Some orphanages are very informal and only go by names. Some of the staff are nurses or doctors so be careful you don't be too informal with them. Most of the staff are licensed workers and they will go by the license name, such as Child Care Worker, Social Worker or Placement Specialist.
