The Evap is the most difficult to get to clear and usually take at least 2 or more drive cycles, but if you get down to one Monitor you may be able to get the vehicle inspected.
My guess is the SAP will not pass due to these engines often having problems with the ports in the head clogging and if the pre-cat O2 sensors are originals, one or more may be lazy.

UPDATE!!!
So I cleared the DTC codes earlier this afternoon, took a 15 minute drive, had 3 monitors showing incomplete.
Took a longer drive first half highway, stopped and waited at curbside for some delicious food, took city streets on the way back, let the car cool down and ate my food....plugged in the scanner and now 7 of 8 Monitors reporting ready!!
The Secondary Air finally cleared, EVAP system hasn't cleared yet, but I can pass emissions without it, Ill monitor it to make sure I resolve any underlying problems, its strange that the EVAP system is the last as its the part I fixed starting this whole process
