Which one of these are not considered shamans?

Easy answer Priest because Priests only practice religion not magic.

Shamanism encompasses the belief that shamans are intermediaries or messengers between the human world and the spirit worlds. Shamans are said to treat ailments/illness by mending the soul. Alleviating traumas affecting the soul/spirit restores the physical body of the individual to balance and wholeness. The shaman also enters supernatural realms or dimensions to obtain solutions to problems afflicting the community. Shamans may visit other worlds/dimensions to bring guidance to misguided souls and to ameliorate illnesses of the human soul caused by foreign elements. The shaman operates primarily within the spiritual world, which in turn affects the human world. The restoration of balance results in the elimination of the ailment.
Classically, a Roman Catholic priest was similar to this. They would do blessings for crops, the sick, etc. Most have turned away from this, and just focus on keeping their people in line.

None of these could be be considered a Shaman in the traditional sense. Although a ‘priest’ (in the broad sense) might be considered one. The Shaman is a Walker Between the Worlds, able to go into the Other Side and perform spells and cures There that would affect the physical body of the patient on this side.
Some types of Curers do this, I suppose, but most do no.
Mediums, Diviners and Astrologers are Definitely Not Shamans.
