What is your question?
I guess...are you trying to understand what software version(s) listed Switches should be updated to?
Mmmm...simple answer: latest for each considered Software Branch (if current and active).
If you have Switches (and you have) that are running on old Software Branches (15.12, 15.15 as examples)...update to latest Software Branch supported by related Switch using the latest Software Version published for that particular Software Branch.
Read (I repeat: Read) and understand what Release Notes reports about each Software Version you're updating to before doing any update attempt.
