Are these diagnostic results considered normal?

It sure would be nice to know what the unit of measure is for each of those categories! But from the looks of the cab ineterior temperature, you are probably frozen to death already. Voltage looks a bit low too.

 

Air temp reading at 6,500 is possibly abnormal? Only if it isn't in Kelvins!
An even then, it's like 3,900 F.

Something might be up with your MAF sensor.

EDIT-Meanwhile, your intake temp is negative 5,200; so apparently, your engine has the ability to create complete and absolute zero. Your Oil PSI is over 200 PSI, as well.

It would seem you have a magic engine, OP.

 

You are looking at garbage information. You are wasting your time. Never use 3rd party scanners to get information like that. We see this sort of thing all the time. As soon as we connect with the proper service tool software such as ServiceMaxx, Diamond Logic, Cummins Insite or whatever, we see the proper information. Not all 3rd party scanners translate the information properly. Also, the big negative numbers are likely due to your scanner not finding any data for that parameter.
But, the most important issue with your numbers is exactly what Hardlyer mentioned, what units of measure is it using? Unless your truck isn't running right, and/or you have a check engine light on, take those numbers with a grain of salt!
