"Raafi'" (رافع) means "one who raises" or "one who elevates." It is among the Asma ul-Husna (the Beautiful Names of Allah), and it is also found among the names of the Sahabah, the most well-known of whom is Rafi' ibn Khadij. For this reason, this name may be chosen for a child.
As for whether "Abd" must be added before it: since this name is among the attributive names of Allah that are not exclusive to Him alone but may also be applied to other than Allah, it is not necessary to precede it with "Abd."
Allah the Almighty knows best.
