Using example data from another thread…
Gui, Add, Button, x22 y150 w90 h20 , Button 1
Gui, Add, Button, x22 y170 w90 h20 , Button 2
Gui, Add, Button, x22 y190 w90 h20 , Button 3
# dummy line, different than the rest
Gui, Add, Button, x22 y210 w90 h20 , Button 4
Gui, Add, Button, x22 y230 w90 h20 , Button 5
Gui, Add, Button, x22 y250 w90 h20 , Button 6
Assuming you wanted all the x22 replaced with x314, Search > Replace..., with ☑ Regular Expression
Find What = (?-is)\bx22\b
Replace with = x314
Assuming you wanted all the various y### replaced with the same y2718,
Find What = (?-is)\by\d+\b
Replace with = y2718
Assuming you wanted all the various y### replaced with a variety of y-numbers, depending mathematically or logically on the value of the original y###, you would use the PythonScript plugin and a variant of the script I showed in that other thread

P.S. :
(paraphrasing @guy038, the forum’s regex guru, who compiled these great regex resources, but hasn’t shared them in this thread yet):
Here is a good starting point for NPP users unfamiliar with regular expression concepts and syntax:
http://docs.notepad-plus-plus.org/index.php/Regular_Expressions
Modern Notepad++ (since v6.0) uses the Boost C++ Regex library, v1.55.0 (similar to the Perl Regular Common Expressions (PRCE), v5.8):
search syntax: http://www.boost.org/doc/libs/1_55_0/libs/regex/doc/html/boost_regex/syntax/perl_syntax.html
replace syntax: http://www.boost.org/doc/libs/1_55_0/libs/regex/doc/html/boost_regex/format/boost_format_syntax.html
