It is not possible for free users to edit record data on the Business plan. It is possible for free users to fill out a form view (or an interface public form, but not an interface-only form). You can then use automations to edit existing records based on the info in the new record that is created by the form. (In Airtable a form always creates a new record, it does not edit existing records.)
If you need multiple people to edit existing data, you may want to look into using a portal service. I list some portal services here.
One of your best bets for doing this is to use Fillout’s advanced forms for Airtable.
Fillout is 100% free and offers hundreds of features that Airtable’s native forms don’t offer, including the ability to update Airtable records from a form, display Airtable lookup fields & Airtable rollup fields & Airtable attachments & formulas on forms, dynamically & conditionally filter linked record fields by any values that you would like, perform math or other live calculations on your forms, accept payments on forms, create multi-page forms with conditional paths, create new linked records on a form, display as many fields as you want to see in a linked record selection list (including attachments), connect a single form to dozens of external apps simultaneously, limit the number of linked records that can be chosen, set advanced field validations & limitations, upload an unlimited amount of attachments simultaneously, add CAPTCHAs to your form, add choice matrixes to your forms, direct integration with hundreds of apps like Calendly & Google Maps on your forms, and so much more.

Nice article, @kuovonne! I really like using Noloco and JetAdmin for my portals — and I am currently using them with several of my Airtable consulting clients — but those are not currently on your list.
Also, Fillout can sort of be seen as a "lite portal"... it's not a "full portal", but can be used as a mini-portal in many circumstances.
Hi there!
At miniExtensions, we've created a third-party portal that integrates seamlessly with Airtable, and allows unlimited end-users to edit their data. This makes it easy for teams of any size to collaborate and manage records directly within Airtable.

If you need certain users to have admin privileges for creating and managing extensions (Forms, Portals or Shared Views), you can add them as collaborators, the number of collaborators you can add depends on your active subscription.
