If you are specifying each of the 5 pressure outlets as "static pressure outlets", you may easily be over-constraining or ill-constraining the problem and trying to force the solver to do unrealistic things. The solver may be telling you this will a diverging residual. Consider your problem again, with a focus on what you actually know. Do you really know the quantitative static pressure at each exit plane? Profile effects? How? If not, perhaps setting one exit to a static pressure outlet (so problem is constrained) and the others as perhaps mass flows would work better. Hope this helps!
