1. I'm not sure but what happens if you use the real filename instead of $2 ?
2. Did you set the newri value before running the command ?

Code:
echo 'rg="333",rh="222",ri="234",rj="567",rk="890"' | awk -F\" '{for(i=0;++i<=NF;){$i=(($(i-1)==",ri=")?var:$i)}}1' OFS=\" var=VAR
rg="333",rh="222",ri="VAR",rj="567",rk="890"

Alternatively you could try:
Code:
var=rh;val=73;sed "s/\(\(,\|^\)$var=\"\)[^\"]*/\1$val/g" infile

Code:
$ cat infile
rg="333",rh="222",rirh="234",rj="567",rk="890"

output:
Code:
rg="333",rh="73",rirh="234",rj="567",rk="890"
