When you create a textdraw (the very first one) it's in the front. When you create another one, it's laying over the other one. So, simply create all the "usebox" textdraws first, then "Behind" and then the "In front". So all you have to do is to move "Textdraw4" to above "Textdraw2" (it's about the "TextDrawCreate" function, all the others doesn't matter when being something in front or not).
I helped a friend earlier with this (not 24 hours ago). You can read it here: https://sampforum.blast.hk/showthread.php?pid=2329268#pid2329268 (This did work for him)
