Measure current of multiple loads with one sensor?
If you're loads are anything other than resistors (e.g. incandescent lamps), or modern electronic devices (laptop charger, new TV, anything with good power factor), then the current measurement alone (times voltage) probably won't give a good measure of the power consumed because of power factor (phase lag between voltage and currents), or distortion.

Can you run all loads concurrently through the sensor, and enable/disable each one in turn ?
