The charge per unit area on the plates is the amount of charge distributed over a specific area on the plates.
Electric potential is the amount of electric potential energy per unit charge at a certain point in an electric field. In the case of two oppositely charged plates, electric potential is the measure of the electric potential energy per unit charge experienced by a charge placed between the plates. It is measured in volts and is proportional to the strength of the electric field between the plates.
The surface charge density on the disks is the amount of electric charge per unit area on the surface of the disks.
To determine the surface charge density of an object, you can divide the total charge on the object by its surface area. This will give you the amount of charge per unit area on the object's surface.
Capacitance increases with a decrease in distance between plates because the electric field between the plates becomes stronger, storing more electric charge per unit voltage. This results in a higher capacitance value since the plates can hold more charge for the same applied voltage.
Potential energy per unit charge is the electric potential, commonly referred to as voltage. It represents the amount of energy required to move a unit positive charge from a reference point to a given point in an electric field. The unit for potential energy per unit charge is volts (V).

The amount of potential energy per unit charge that a static charge has is equivalent to the electric potential at that point. For electric current, the potential energy per unit charge can be calculated by multiplying the electric potential difference across the circuit by the amount of charge.
That's not enough information to find the charge. You can find out the surface area with that information, but to actually know the charge, you would also need to know how much charge is stored per unit area.
The capacitance won't change, or it won't change significantly. The capacitance is simply the charge/voltage ratio - and if the charge doubles, the voltage will also double. Capacitance is determined by the physical properties of the capacitor (plate separation, plate area, and dielectric). The unit for capacitance (farad) is a coulomb per volt. So the capacitance is the amount of charge (coulombs) that the plates will hold at a given voltage.
Pressure is defined as force per unit area.
