.If one input is ON nothing happens
.If at least 2 inputs are ON a red pilot light (R) goes ON

You will need four logic expressions, one for each output. Just make them ORs of the ANDs of all combinations of the inputs that can cause the output. For example, if the inputs were A, B, C, D, the red pilot light output would be all combinations of two inputs:
A*B + A*C + A*D + B*C + B*D + C*D
where “*” is AND and “+” is OR
