so, ran into a bit of a snag

I need to number the files in the order they are processed.

-o FILENAME write PNG image to FILENAME. If '-' is specified, the result
will be output to standard output. If -S is given, structured
symbols are written to FILENAME-01.png, FILENAME-02.png, ...;
if specified, remove a trailing '.png' from FILENAME.

if I try

for x in `cat add2.txt`; do qrencode -o -S $x.png $x; done

it does a single file named -S

ive tried

$-.png

$'-'.png

for x in `cat add2.txt`; do qrencode -o -S $x.png $x; done

for x in `cat add2.txt`; do qrencode -S $x; done

I dont understand "If -S is given" trying to get the -01 -02 -03 ext

the -S needs to come before the -o and you need to remove the .png from the filename.
altho I don't understand why do you want that option, given that the files will already be numbered.
