Need a formula to prepare SLA report

SLA
Critical = 4 hours
High=8 hours
Medium= 72 hours
Low=120 hours

If the ticket is closed within the SLA then the result should be “Within SLA” else “Exceeding SLA”

Attached is the only data available through the system. I tried to use the status, priority and created date to achieve this but no luck.
Yellow cells indicate data extract from the system.
Appreciate if someone could help me with the available data.

Welcome to the Forum!

I'm having trouble figuring out what your question is. Assuming that the Created Date and Resolved Date are correct, everything else you have to the right of that seems to work as expected. For the elapsed hours, I would use the formula

=(H1-F1)*24

because yours truncates and mine is exact, which matters if you're calculating compliance to SLAs. But other than that I don't see what is giving you trouble.
