If the fluids are miscible (i.e. they will mix), you can create a variable composition mixture of the four fluids and specify appropriate mass fractions for each fluid at the corresponding inlets and your initial conditions.

If they are immiscible (i.e. they do not mix, such as water & oil) you can choose them as multiple fluids in a multiphase analysis, specify the free surface option and specify surface tension as necessary.
