It is possible for your organization to use a free plan in Airtable, which allows unlimited collaborators on a workspace. As long as your collaborators have Airtable accounts, they can be added to the workspace, even if they are not actively using it. However, some advanced features, revision history, and backups are only available on paid plans.
To create a new workspace with just two collaborators, you can go to your Airtable dashboard and click on the "Create a workspace" button. From there, you can invite your collaborators to the new workspace by entering their email addresses. There is no need to upgrade to a paid plan for this, as Airtable allows you to create multiple workspaces on the free plan.
I hope this answers your question, and please let me know if you have any further inquiries

If your existing workspace is a free workspace, it must be a legacy free workspace. If you create a new free workspace, you can have a maximum of 5 owner/creator/editors.
On the other hand, you might have some confusion about who is paying for the workspace and how. Individuals on the base who are creators do not pay for their accounts. Rather one of the owners of the base pays for all the billable collaborators. it is also possible (but unlikely) that the account has somehow enough Airtable credits that the owner has not been charged in a while.
Unless your organization has an enterprise license, billing for Airtable occurs on the workspace level. So if you create a new free, plus, or pro workspace, it will have its own billing independent of any other free, plus, or pro workspaces.
