Luminosity is the total power output of a star. Think power = intensity x area. Intensity or "flux" is basically the power at a certain spherical distance away. So the sun will have an intensity of a massive figure, but here on earth the intensity is much less as it decreases by 4πr^2

fairly, yes, although its a fine detail and one that examiners will probably give you marks for either one. Just make sure you dont mix up luminosity and intensity.
