I would like to uninstall Google Hindi and Google+ which I have no use for but if I try I get messages that it may cause other apps to misbehave. Is this true?
Do you mean you want to Disable those apps? You can't completely uninstall Google+ (not sure about Hindi) unless you're rooted.
That message is standard. Disabling Google Hindi will certainly be fine. If you Disable Google+, you might not get access to the new Google Photos app (although if you have the stock Gallery app, that should still work for you).
