The 235/75/16 is larger.
A 235 85 16 tire is 31.72 inches in diameter and has a 15.86 inch radius and a 99.65 inch circumference
Speedometer reading will be over by 3%.

Yes you can
Yes you can
You can but you should not. The 235/85-16 tire will be way too tall and will have a diameter that is 2.22" larger. This will cause your speedometer to be 4.2 mph too slow at 60 mph. This is not a good swap.
Doubtful, the 225/65 tires are narrower and shorter.
Can you? Yes. Should you? No. The 235 will be 3.67% smaller. This will adversely effect your ride, handling, speedometer, and braking.
That should be OK, but check carefully for any rubbing.
Maybe, if there is clearance for the wider tire.
I guess you can - 235 85 R 16 is a bit narrower and taller. but not vitally. so it would fit
That size will work but your speedometer will be off .8 mph too fast.
The way you have phrased your question is confusing. If you are saying that the 235/70-16 is the OEM size the answer is NO, this is not an acceptable swap. Going either way this is a bad swap. If your OEM size is 235/70-16 and you want to go to a 75 series tire then you need to install a 215/75-16. If your OEM size is 245/75-16 and you want to go to a 70 series tire then go with a 265/70-16.
That should be OK, but check carefully for any rubbing.
No, the 255/70-16 is too large and the diameter will be 1.10" too tall and your speedometer will be 2.2 mph too slow. You are going over 3% difference in size which is never advisable. You can use a 245/70 or a 245/60 but not a 255/70. Make sure all 4 tires are the same size on a 4wd vehicle.
