Go to Splunkbase page for all those app and see if they're compatible with Splunk 8.2.2. If they're you don't have to upgrade (you may want to read the Release Notes for newer version of apps to see if a new feature got added that you might like).
If the existing version of each app is compatible with 8.2.2 then there is no need to upgrade that app. If a newer version is needed to be compatible with 8.2.2. then upgrade the app. Splunkbase will have this information.
