On the last Starship flight (Orbital Flight Test 2), all 39 Raptor engines started up and apparently ran correctly. On the next flight, will we see all engines operating correctly when they get a chance to do so?

This includes proper operation for the entire flight of both stages. Uncommanded shutdowns, engine explosions, and failed relights will all result in this resolving No, with the major caveat that this must be attributed to engine problems. If, as has been suggested happened on flight 2, engines fail because of stage problems, tank problems, propellant slosh, tank depressurization, or other related problems, that will not result in this resolving No.

There is no requirement for a successful landing, completion of second stage flight, etc.

If the flight is other than nominal, resolution of this will probably have to wait until after the flight for a mishap report or other credible reporting.
