It seems that some people consider these base units, some don't. You might want to make up your own mind about what you think about this point. However, I would go for "derived unit", simply because that's the official definition.
A radian is used to measure angles; the way it is defined is by dividing an arc on a circle by the radius; so naturally, the units are meters/meters. Or substitute any other unit of length for meter, such as angstrom/angstrom or AU/AU or light-years/light-years; but the result would be exactly the same. In other words, it's a dimensionless unit.
The same applies to the steradian, which is radian2. This, of course, is also a dimensionless unit. It is also officially considered a derived unit.
The basic SI unit for mass is the kilogram (kg).
No.* Mass is measured in kilograms. * Volume is measured in cubic meters (which is not a base unit, but a derived unit).
The basic unit of electric current is the ampere (A), which represents the flow of electric charge through a given point in a circuit per unit of time.
The basic unit of measure for frequency (Fr) is hertz (Hz), which represents the number of cycles or oscillations per second.
