No. The sanctuary is where the congregation gathers for worship service. The entry hall (front?) is called the "vestibule."
The area where the congregation sits is called the "nave."
The area where the sermon is delivered is called the "alter," or "pulpit," depending on the design of the church. Sometimes there is a pulpit structure on the alter, and sometimes the sermon is delivered from a lecturn.
Of course there are many different churches and many different designs. But this is what we called the areas in the church I grew up in.
Sanctuary
In a historic floor plan of a church, the area between the altar rail and the pews is a boundary where the floor of the chancel is higher than the floor of the nave. The sanctuary can be the front part of the church where the service is conducted or it can mean the nave and chancel together.
It is called the Narthex.
Pulpit is a speakers' stand in the front of a church. Typically, the one on the left (as viewed by the congregation) is called the pulpit. Since the Gospel lesson is often read from the pulpit, the pulpit side of the church is sometimes called the gospel side.
It depends what you mean. There are different parts of the church, some areas are used for some ceremonies and not for others. If you mean the main part of the church, the chancel is the front part, usually elevated, where the altar sits and also called a Sanctuary. The nave is the name given to the architectural area people gather to worship in. If there is no elevated platform then the whole area can be called a Sanctuary because there is no defined difference in the spaces. It also depends on the church and how the church is built and set up really. Some have a chapel, others don't. Some have a Baptismal font for Baptism, others don't. Some have a specific prayer room for tabernacle, others have the tabernacle in the Sanctuary or other location in the main church itself.
Originally, all Catholic Churches had an altar rail, which was a horizontal bar of wood, marble, or metal, supported by vertical posts the separated the sanctuary from the body of the Church. The altar rail also served as a Communion rail when the Eucharist was given to kneeling communicants. The gate was for the ministers to pass through on their way to and from the sanctuary.

This is so that one may bless oneself with holy water, removing venial sin from ones soul, and preparing one to enter into the Holy presence of God. The font is at the back of the Church- the Alter is at the front. If the church is oriented (that is, the sanctuary is in the eastern end and the entrance in the west) the font is usually found in the west.
A church tower is called a steeple. It is often a tall structure, typically located at the front of the church building, and may contain bells or a clock.
