Load files in sequential order

I need to load multiple files in my shell script with the same filename but appended in the front of each file name is YYMMDDPERSONNEL Examples: 231102PERSONNEL and 230103PERSONNEL There are many other files in the same directory so filenames are important in the sort. I need to sort files to be loaded from the oldest to the newest. Currently what I have is only designed to handle one file at a time.
