Baptism must be received before any of the other sacraments are open to you. It is not a mere formality - in order to receive Christian sacraments one must be a Christian. Baptism leaves a permanent character upon the soul, identifying it before God as one who has received the New Covenant and thus the graces of the New Covenant are made directly available to the soul through the Church of which the soul is now a member.

Our Blessed Lord is in the sacraments in a very real way. THE Sacrament of Sacraments is the Eucharist, which is His Blessed Body and Blood. Starting with the Last Supper, Our Blessed Lord gives Himself to us under the appearances of bread and wine. In the other sacraments, He is present and gives His grace to those who receive those sacraments in a worthy manner, but He is not actually present in the same way that He is in the Eucharist.

In few situations are they permitted both, but the Catholic church examines marriage of clergy members in special situations on a case by case basis.
In the Catholic Church, baptism is generally required before receiving the other sacraments. Baptism is seen as the gateway to the sacraments and the initiation into the Christian community. However, there may be exceptions made in certain circumstances, such as the sacrament of confession or reconciliation in cases of emergency or danger of death. Ultimately, the requirements for receiving sacraments can vary based on specific circumstances and the guidelines of the church.
Holy Orders is the sacrament through which a man is ordained as a deacon, priest, or bishop by the laying on of hands and prayer. This sacrament conveys a special grace and power to serve the Church and administer the other sacraments. It is one of the seven sacraments recognized by the Roman Catholic Church.
I have no idea what you mean by your question. Confirmation is a sacrament in itself and is not subdivided into 5 other sacraments. Maybe you can clarify your question so a correct answer can be provided.
Baptism is the sacrament of initiation in which one becomes a child of God. It is impossible to receive any other sacraments without first receiving Baptism. Sacraments are real, physical acts but they are also symbols of the grace which is received from God. Trying to receive another sacrament without Baptism would only be going through the motions.
The sacraments at the Service of Communion is from the Catechism, the header for Chapter Three of Part Two: Question 1533 names Baptism, Confirmation, and Eucharist as the Sacraments of Initiation. In 1544 It mentions two other sacraments, Holy Orders and Matrimony directed towards the salvation of others. These five sacraments are "at the Service of Communion".
