  It partially depends on the plugin. The one guarantee you have is that there will be a row in the `plugins` table. Go ahead and delete that row.
  
  Some plugins create 3rd party tables. For *most* of those plugins, it's probably safe to just delete those tables as well.
  
  I know you can't go back in time, but... the *best* solution would have been to remove those plugins *before* updating. Virtually all Craft 2 plugins did a good job cleaning up after themselves in the database.

  * **Form Builder 2** - Not very familiar with this, but looks like it has 5 tables. Probably safe to delete them.
  * **AmForms** - Another one with 5 tables. Probably safe to delete these as well.
  * **Hacksaw** - No DB tables
  * **Shortener** - No DB tables
