The deacon and priest venerate the altar by kissing it. Whetherr or not they lay hands is up to them, and nothing forbids that for either priest or deacon. The rite only calls for the kiss; I suspect the "laying of hands" on the altar is more for support
Acolyte or deacon or altar server
To venerate means "respect"... At the entrance of Mass, the priest bows to the ALTAR, genuflects to the Blessed Sacrament (different forms - respect vs. adoration) ascends the steps of the altar, places both hands on the altar, bends to kiss the altar, rises... begins Mass. Should a deacon assist... at the entrance the deacon bows/genuflects... kisses the altar, but does not place his hands upon the altar.

The priest wears red because that is the color that is called for on Palm Sunday, thus the altar should be red as well.
In a Catholic Mass, the Book of the Gospels is typically carried by the deacon. If a deacon is not present, a priest may carry it. The Book is usually processed during the entrance and placed on the altar, symbolizing the importance of the Gospel in the liturgy. The act signifies reverence for the Word of God as it is central to the celebration of the Mass.
Roman Catholic AnswerAt its bare minimum, there are only two: an altar server and a priest; and the altar server is optional if there is no one available. At a Sunday Mass in a parish, you might have a priest, a deacon, one or more altar servers, a reader, one or more Extraordinary Ministers of the Eucharist, a cantor, and people in the choir; not to mention the congregation. Again, only the priest is necessary, though.
A priest was standing on the altar in the church.
The young priest assigned to a parish to help the pastor is called a curate. The young men who assist the priest at the altar are called altar boys, or sometimes altar servers if the priest in question insists on letting girls help.
The priest and deacon prostrate themselves before the altar at the beginning of the Good Friday services as a sign of deep reverence and of deep anguish for the suffering Christ.
