Question about Toyota Camry
Switching coils is not the way to resolve that issue
At home,no experience,no test equipment, all you
can do is walk a new coil, one cylinder at a time &
drive at least 20 miles in hot weather if possible
You don't have the ability to check fuel trim or an
easy way to check for vacuum leaks.
You also can't check cylinder contribution for
mechanical problems,that should happen first
Walk a new coil,putting back the old one as you go
The codes are not always correct or you get many
that make no sense.
If one coil is bad & 7 years old the others are not
far from acting up also
Those coils do many different acts on different engines
No PO300 will tell you if you have a bad coil or what one
I have seen professional scan tool software not work,
& your back to the coil walking

P0420 indicates you have a catalyst efficiency issue; replacement of the Air-Fuel Sensor should take care of that;
The P0441, P0446 and (I assume P0440); you said 446 twice, indicates a faulty or loose fuel cap; it is not sealing properly.
Please feel free to respond to me if you have any further questions.
A FixYa rating from you regarding my assistance would be greatly appreciated.

P1410 EGR Valve Position Sensor Circuit Malfunction
You may have to replace the sensor. If you get a chilton manual at an autoparts store, it will show you how to test the sensor with some test values in the book. The book should run about $20

Get a T belt from toyota. It has 3 white lines on
it and and arrow mark. 2 lines are solid and one is broken. Put the
arrow facing away from the engine. The cam gears have a dot punched
into them near a certain tooth. This is where the solid white lines
will line up with. The crank gear will have a dot also. It will line up
at 90 degrees from the top, towards the front of the car. This is where
the broken line will match up with. With the belt installed with all
lines on their proper dots and arrow away from the engine, you valve
timming is correct.
Of course you need to remove and compress the tensioner also. I assume you know this already since you didn't ask.

Perhaps the compression guage u used has a defective schrader valve, if the compression was that low it would run bad, and mileage would not be 19 MPG. Glad to hear all is well.
