Doubt 7 and 9 are related to EGR fault
But 7 can be coil tower resistor connectors [ thus bad idle]and 9 can be IAT sensor unplugged at cross-over pipe or someone unplugged it while running and did not reset the code..
Also, on code 5, if you find egr valve does operate normal w/vac test, then look at the plastic vac line that feeds the SOV for EGR circuit...these are famous on 104s for breaking from heat fatique and will pop a 5 code
[ front of engine, under plastic cover]
I always eliminate the plastic tubes and go full rubber....
