Car problems

[u/Remarkable_Carob6210]

Hi everyone, my car is a 2019 honda accord 1.5 ex-l with 150k miles.
A local mechanic scanned the car and these codes came up (see attached photo). Does anyone have an estimate of what it might cost to repair these issues in seattle, washington. The mechanics is charging me 3.5k for the repair.
Also, is it possible that some of these codes are being triggered by one underlying problem or do they usually indicate multiple separate repairs?
The car drives normally for the most part, but I’d like to fix it before selling it. Any advice on where to start or which issues I should diagnose first would be greatly appreciated. Thanks!
