In the hierarchy of the Catholic Church, a priest has more authority than a deacon. Priests are ordained to celebrate the Eucharist, hear confessions, and perform other sacraments, while deacons assist priests and perform specific duties, such as baptisms and preaching. Deacons do not have the same sacramental authority as priests. Therefore, within the clerical structure, priests hold a higher position of authority.

The term deacon comes from the Greek word "diaconos" which means a servant. However, in the Christian Church, the term is mainly used to describe a man who is training to become a priest, and is the first 'order' of clergy before being made a priest, but he can also remain a deacon without later becoming a priest. The three levels or 'orders' of ordination are deacon, priest, and bishop. In most cases, a deacon acts as an assistant to a priest.
A transitory deacon is a person who will be ordained a priest. All priest are first ordained as deacons. A permanent deacon is a person who will remain a deacon for life, unless at some future date he decides to become a priest and is ordained to that order as well.
Levels of progression: Deacon, Priest, Bishop, Arch Bishop, Cardinal, Pope A deacon is not a priest everyone else is.
Deacons have pretty much the same authority as priests when it comes to blessing items and homes. A gift to the priest or deacon that makes a special effort to come out and do you a favor is always a good thing, but it is never required. Charging for sacraments or sacramental is known as simony and is a very bad thing. In other words, you may offer something to the priest, but you may not "pay" him.
a deacon
No, a deacon cannot hold up a consecrated host at the altar and say "the body of Christ" during the Mass. This action is reserved for the priest, who alone has the authority to consecrate the elements and perform the Eucharistic prayer. The deacon may assist in the distribution of communion but does not have the role of consecrating or elevating the host in the same manner as a priest.
Baptism - normally a priest or deacon. In an emergency anybody. Confirmation - normally a bishop. With permission, a priest. Reconciliation - priest Eucharist - the priest consecrates, deacons and extraordinary ministers can distribute. Marriage - priest or deacon Anointing - priest Holy Orders - bishop
St. Francis was a friar - a brother. He was was not a priest. However, he was eventually ordained as a deacon.
Acolyte or deacon or altar server
Both can, deacon is still ordained just a lower rank so if both present appropriate for priest unless he defers
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
