If in a circuit, current lags behind the voltage then the
resulting power factor is said to be lagging. Ex: Inductive
loads.

If in a circuit, current leads the voltage then the
resulting power factor is said to be leading.
Ex: capacitive loads.

Power factor is the ratio of real power to reactive power.

Define demand factor?
