they look pretty bad, as suspected from a cold start values are much higher than your last readings.
I don't know the firing order on the 5 pots , but for sure issue with cyl 5 and possibly 4 the others might just be compensation for those one or 2, ie if 5 is bad and fixed all other values will go closer to zero anyway.
it sounds pretty bad in the vid even after a bit of a warm up.
id be working my way up the list of cheapest fixes first, or a trip to likes of autolusso.
id still like someone to confirm an accurate test for a bad connection in the injector plug or loom issue.
did you try playing with plug/wires whilst logging values, see any changes. It sounds like missing one cylinder, even try unplugging cyl 5 and 4 in turn see if anything changes.
ps if you do get any tested I recently used this guy to test some, was much cheaper than a local place
he did discount for 4 or more I think was £50 for 4 (after messaging him)
I think its not million miles from you, mine were not off the car so I wasn't desperate, but they were a bit longer than expected. ash was the guy I spoke to (as he phoned to explain some failed)
typical test sheets from him are here post 217

no idea what repair cost would be as had none done just tests.
