Answer 1

It appears that you're using a shared spreadsheet to collect the add-user-requests, and trusting the requesters to fill in the information. In the detail document you shared, it further appears that requests are ADDED, but not EDITED. (That's an important simplifying distinction.)

I suggest that what you really need is to use a form for receiving that input. Using a form will create a "data table" within your spreadsheet, a set of columns that you must not mess with. (You can edit the contents, add and delete rows, but must not add or remove columns.) However, you CAN add columns to the spreadsheet outside of this table, which gives you a handy place to store state information about the status of individual requests.

Further, you can trigger your processing to run on form submit, rather than a simple "onEdit" - this gets away from the problem that ScampMichael pointed out. Alternatively, you can use an installable edit trigger, as described in this answer.

Try this sheet, and this form. Save yourself a copy, go into the script and remove the comments that are stopping emails from being sent, and try it out. There's a menu item in the spreadsheet that can kick off processing; just clear the "Request State" column to re-run it. You can open the form (and find its URL), and add more entries to experiment.

It's the core of a similar system that I've written, and contains a discreet state machine for processing the requests. My system has large amounts of very complex data in multiple spreadsheets, so it often gets pre-empted, then needs to run again. (I use a timed trigger for that.) That's why requests are handled through states. If you find that too complex, pull out only the parts you need.
