right now I can achieve this with sed -i in while loop:

$ cat reference|while read a b;do sed -i s/"$a"/"$a($b)"/ input;done

Could it be done in an easier way, using just the awk and without the while loop, using input and reference file in single awk command processing changing the values only in second column?

The following approach is purely awk-based and avoids the external loop:

awk 'FNR==NR {key[NR]=$1; ref[NR]=$2; n_refs++; next} {for (i=1;i<=n_refs;i++) if ($2==key[i]) $2=key[i]"("ref[i]")"; print}' reference input

This will process first the "reference" file and generate a list of UUID-"Group nr"-pairs (actually two arrays with corresponding entries) from that file.

Once this file is processed (indicated by FNR, the per-file record number, differing from NR, the global record number), and the "main input file" is being processed, it will loop over all associations found and add the group ID corresponding to the UUID in second column by simply comparing the current content of the second column to all registered UUIDs.
