The awk solution below first stores the low-high file into an array.
As it passes and prints the main file, it notes which "POINT_NAME" is passing by. As LOW_ALARM and HIGH_ALARM lines go by, awk rebuilds those lines if values for that POINT_NAME are in the array.
The BEGIN processing stores the low-high file using default white-space field separation. But it then sets the Field Separator to a double-quote sign for processing of the main file because it makes the coding cleaner and more precise. With this field separator, each tag and each value become a separate field, and thus a little cleaner to identify.
Just for testing, I add (UPD) to the end of lines that I rebuild. I do not test to see if the value actually changes, so the (UPD) just means that I rebuilt the line with a value from the low-high file, even though the value could have remained the same.
I did not rely on POINT_NAME always being the nth word in that header line. I scan the line to isolate it.
