Firstly I would have all the codes cleared (after writing them down). then see what pops back up.
From what is there at the minute , I would then gas test to see what exhaust is doing whilst live probing the lambda sensors to see what they're doing.
Once all the relevant tests have been done you will have a better understanding of what needs changing.
Going by what the codes show at the minute, all 4 coil packs. both lambda probes, coolant temp sensor. BUT once tests are done you might only need a lambda probe, cos all the other codes are BECAUSE of one component being faulty and not all of them.
Diagnostics are great not
