@Camilla *******
sheesh, okay lemme try one more time
You came in on a 60 day tourist visa entry and a 30 day visa exempt entry,
you BOTH took the one 30 day "regular" extension
you then BOTH got a 60 day covid extension
are are now asking IF you can get another extension?
Did I finally get it right?
If that is true then you do indeed qualify for being able to apply for another covid extension. NOW whether the office you apply at will issue it is between you and the officer you're sitting in front of when you apply. They could ask for proof of onward travel within the 60 days that the new extension would cover.
As long as you go apply before this current covid program runs out (March 25th) you could try to apply for one. There is nothing OTHER than the 60 day covid extension you could try for so it's either that OR leave when your current stamp is up
