Multiple Gmail Accounts Inaccessible After One Ban

I have several Gmail accounts that I can no longer access properly. This problem started approximately 2–3 months ago. One of my Gmail accounts, which was linked to my Facebook, appears to be banned after someone apparently reported it. After that, although only one Gmail account was banned, I can no longer open or access my other Gmail accounts either. I have already tried the usual recovery steps such as the account recovery options, but I still cannot regain access. At the moment, I am effectively locked out of all my Gmail accounts even though only one account was banned. I kindly request that my Gmail accounts be checked and that access to my other accounts be restored, or that I be given a clear recovery method so I can use them again. I would like support and clear guidance on how I can safely recover these accounts.
