No, "dimensionless" means, precisely, that there are no units.
No, a quantity cannot have units and still be dimensionless. The dimensions of a quantity are determined by its units, so if a quantity has units, it has dimensions. Dimensionless quantities are those without any units.
No. "Dimensionless" means there are NO units involved.
The mass is not dimensionless; it is a fundamental physical quantity that describes the amount of matter in an object. Mass is typically measured in units such as kilograms in the International System of Units (SI).
Angular momentum is a vector quantity and therefore has dimensions of mass multiplied by length squared divided by time. In SI units, the dimension of angular momentum is kg * m^2/s.
A quantity with square units typically refers to a measurement of area. For example, if you have a square that is 5 units by 5 units, the area would be 25 square units. Area is expressed in square units because it represents the amount of space enclosed by a shape.

they show the magnitude
No. The dimensions are: Mass, Length, Time, and Charge. They transcend the systems of units. For example, speed will always have the dimensions of (Length)/(Time), regardless of the system of units.

The dimension can't be determined here since 4 cubic feet is actually the quantity of the volume units. "cubic feet" doesn't determine the dimension. It determines the volume of the object.
Electrical charge is a fundamental dimension all by itself, and is not derived fromany other fundamental units. The unit of charge is the Coulomb, which is definedas 1 ampere-second.
A quantity with square units typically refers to a measurement of area. For example, if you have a square that is 5 units by 5 units, the area would be 25 square units. Area is expressed in square units because it represents the amount of space enclosed by a shape.
When you take the logarithm of a quantity, the units of the quantity are removed.
