I looked for your account details however, I could not find any active/trial subscriptions associated with the account. Have you subscribed using a different email address?
those aren’t valid serial numbers (which is fortunate, or maybe you prudently truncated the numbers, because posting serial numbers in public is one of the ways to invalidate a serial number).
but assuming you have valid serial numbers (6 groups of 4 numbers), you can still activate cs5 (but not acrobat 9):
now, assuming you’ve tried a valid serial number with cs5 and have seen an excess activation count message, there's now only one way to deactivate, now. in the past, there were several ways including asking adobe support to reset your activation count, but that no longer works.
use the computers (if they exist, still run AND can communicate with adobe's deactivation server) with the activations and open an app > click help > deactivate. if you've already uninstalled the app before deactivating, but still have an operable computer, you can reinstall on that computer and then deactivate.
that doesn’t include legacy (eg, non-subscription) apps.

the big catch is can those computers communicate the deactivation with adobe's servers.
