Correct: it is a dimensionless number.

A dimensionless number has no units. The units of all variables that compose the dimensionless number (product or ratio) must cancel each other.

Yes, the magnitude of a vector is a scalar.

A dimensionless unit - an integer (or counting number)!

Specific heat is dimensionless, and dimensionless units have the same value in any system. Specific heat is the ratio between two densities - that of the substance considered, and that of water. The ratio of two quantities of the same dimension will naturally be a dimensionless number.
