Briefly put, the path loss model is used to calculate the mean signal attenuation, while fading/shadowing models are used to calculate the variance of the attenuation.

All the path loss models except Log-distance are 'fixed models', which means that the model parameters are fixed theoretically. Only the Log-Distance model allows you to change the path loss exponent.

The fading models - Rayleigh, Nakagami - and the shadowing models -- Log-normal, Constant - allow for parameter variation.
