Reauthorize devices after removing them with 'deauthorize all button' .
After deauthorizing the five or four devices current in my account I wish to return them to an authorized setting . Thank you , FRP .

Authorize them the same way you would if they had never been authorized before. See instructions in: Authorize or deauthorize your computer for iTunes Store purchases - Apple Support
Note that Deauthorize All and Authorize only apply to computers, not to iPhones or iPads.
