If those layouts exists in the database then I’d expect that they are in the CMS itself as well - perhaps they are retired now?
You can certainly access the MySQL database the remove those layout records from it (not edit this file directly but access MySQL on docker), but first I’d look in the web ui to see if they are there (as mentioned perhaps with the retired filter set to yes if you don’t see them in the standard view).
Generally you should not need to make any direct changes on the database.
One of the names that you highlighted has template in it, which could imply that it could be an actual template, you can check it in web ui on the Templates page.
