1. The filter order n is the number of opamp stages in each branch. In this case you've chosen n=3

2. The number of paths is 2, no matter what. The 90 degree phase difference appears between the outputs of the two paths.

3. Referring to the figure you posted, the values of R1 and R2 have nothing to do with the R1 and R2 values displayed by the software (a bit confusing yes). You can arbitrarily pick R1 and R2 for all stages/paths, so long as R1=R2.

4. The R and C values given by the software refer to C3 and R4 values in that schematic (again, confusing). Each row in the table is a stage in the path. The left table (R1 and C1) is for one path, the right table (R2 and C2) is for the other path. The ordering of stages doesn't actually matter (in theory).
