How do i make my 5th/6th ports work on S4 N/A?

troubleshooting sucks
i wondered the same thing. the sleeves on the usdm versions seem to have so much metal to metal surface area when installed in the ports its no wonder that most of them rust in place when left unused for a while. also the fact that the butterflies are always open seems better than being shut in case they stopped functioning it would be much less of an annoyance in comparison.

so if I wanted to keep them working on a s4 will I need the vaccum spider, air control valve, and airpump?

if you want it to work properly, yes. otherwise you could use the exhaust backpressure if you tune it to open when you want them. downside to using exhaust gas is it isn't very easy on the passages and diaphragms that it will be controlling.
