Question 1: When I choose "Did not open any of the last 5 campaigns" does that mean "Did not open any of the last 5 campaigns that they received"? For example, I've sent some campaigns to only some of the subscribers in a list. The wording is ambiguous.
Did not open any of the last 5 campaigns would mean only the ones they received, yes.
Question 2: "Did not open any of the last 5 campaigns" probably means that the subscriber opened none of the last five campaigns. Unfortunately, it could also mean "Of the last five campaigns, were there any that the subscriber did not open. Can someone confirm that the first interpretation is correct?
No, it means the second. Out of the last 5 campaigns they received, they didn't open all 5 but they may have opened at least 1. If you want only non-readers, use one of the "All of the last X campaigns" options, which would mean that out of the last 5 they received, they weren't recorded as reading any of them.
Question 3: I can understand what "Did not open" or "Did not click" means. I assume that "Finished Sending" means that the campaign was successfully sent to the subscriber. Is that right?
Yes. I believe this is one you mostly would see if you have a paid account and used the pulsed send out (where it sends out in batches), so you don't end up sending a second email to someone who hasn't yet gone through the queue for the first.
To segment off potential non-readers, I used Campaign Activity did not open All of the Last 20 campaigns and did not click all of the last 20 campaigns. This weeds out anyone who may be opening or clicking some emails, but not necessary all of them (particularly since my list also includes a monthly blog summary send out).
