Yes, all sugars rotate the plane of polarized light.

Explanation:

The direction and the amount of the rotation vary from one sugar to another.

For example, the specific rotation, [α]_"D"^20#, of D-glucose is +52.7°, while the specific rotation of D-fructose is -92°.

The specific rotation of sucrose (common sugar), ${\text{C"_12"H"_22"O}}_{11}$, is +66.5°.
