You can find the download files of iOS 8.4.2 on your Mac, however since Apple stopped signing iOS 8 days after iOS 9's release it's anyones guess if it would work. Try it see what happens. Once you've dowloaded any of the iOS 8 versions, connect your iPhone to iTunes, Hold Option+restore and click on the iOS 8 version and it will begin.

Yeah you can downgrade to any OS X version if you want. That doesn't work for iOS though (except for a short time, usually 2 weeks, when Apple still sign the previous version).
Definitely make sure to back up your devices before updating so if you don't like the new update you can go back to that previous version. Besides that I don't know of any way to go back to 8.

That's not going to work since Apple stopped signing iOS 8. The only way to downgrade at this point in time is to find and use a jailbreak. And even at that, it still may not work. Once you upgrade, the usual result is that you have to live with it. :(

Even if you make an iTunes backup before updating it won't work, if you restore your backup you will still be on the latest iOS. There is really no way as of today to downgrade to iOS 8.

Not only back up, but archive the backup, because (for example) you can't restore an iOS 9.0.2 backup to a device that's running iOS 8.4.1. But you still have to be going back to a version of iOS that Apple is still signing.
