How to understand the bizarre high level for both PM2.5 and Ozone
I think it is important to keep in mind the mechanisms that form PM$_{2.5}$ are different than the mechanisms that form O$_3$. 

From the data your provided you can draw some simple conclusions:


Increasing SO$_2$ increases PM$_{2.5}$
Increasing NO$_2$ increases PM$_{2.5}$
Increasing NO$_2$ doesn't necessarily increase O$_{3}$


The last point is what you seem to be struggling with. I think what you see here is 'the weekend effect' where lowering the NO$_2$ concentration increases O$_3$ concentration. In this effect, the generation of nitric acid and the destruction of O$_3$ by NO ($\ce{O_3 + NO → O_2 + NO_2}$) decreases the ozone, but increases NO$_2$. I think this explains the phenomenon seen.
