Connect your phone/tablet to iTunes and just hit 'update' button while holding 'option' key on your Mac keyboard, then select 9.0.1 IPSW file (which you have to download from the internet).

I believe you couldn't make backups on the iOS 9 betas, but, if I'm incorrect, common sense tells me that you can use a beta backup on iOS 9.0 or 9.0.1 because it's future software.

You could make backups during beta. (Mine was backing up no issue every time I plugged in.) The only thing was they wiped all iCloud backups around the 9th when they released GM. This was to get rid of the phantom backups some were getting and couldn't delete. But backups worked again since the wipe without issue (for me)
You can't, unless it's iTunes backup with modified version.plist file. However, if you want to downgrade your iOS version, the method I described earlier is easy to do.
What Prabas is saying is that method works like an "upgrade" so no restore of backup required. But to answer your initial question, no, iCloud backup will not restore a newer iOS version backup to an older iOS version.
