I don't think it's clear what you want. Can you restate your goal and give another example?

I'm sorry, I still don't understand what you need. What have you tried so far?

Your files doesn't contain data structured in columns. First file contains only the names of files and other files seems to contain lines with some unstructured text data. So, I don't see any advantage why it should be done in awk. I would do it in other scripting language. However, if you want to do it in awk, you can, but first make a little effort, try to write something self, post here your code, say us where are you stucked and then ask your questions. Please be clear that this is not a free coding service.

Not a sign of the word AWK anywhere I'm afraid but if I have understood the op's question this would do it ...

 for _FILE in `cat file_1`; do if (fgrep -epattern1 -epattern2 $_FILE) then perl -pi.orig -e 's/pattrn3/ChangedIt/' $_FILE; fi ; done

Assuming the OP was wanting to:

1) Go through a list of files that are listed in file_1
2) for each of those files look for a match of the two strings pattern1 AND pattern2
3) if that matches both strings then if pattern3 is also in that file then rewrite pattern3 to something else in the example above to "ChangedIt"
4) If not either of 3 then just move on
5) Oh and in my case I backup the original file to .orig
