If all things have moment of inertia then a swinging sphere with water filled must have moment inertia too? Then can we analyse it as an approximate case of angular simple harmonic motion?

Sure. Just don't forget that if you rotate the sphere, the water will heavily impede the rotation.

I can't see how water will impede motion.
Anything to do with viscosity?
