You're almost there... no need for the single quotes, and you can separate commands using ";", e.g.

sed "s/$esid/$sid/g;s/$emount/$mount/g;s/REUSE/SET/g;s/$ESID/$SID/g" temp>temp1

Thanks alot Annihilannic...

It's because you changed the double quotes " to single quotes '.

Single quotes prevent variables from being evaluated.

So many thanks Anni..I have learnt somany things from u...

You can use cat here to appaent dummy file to dum:

cat dummy  >> dum

Or, of course, cat dum dummy > newfile. This is what cat was designed for, concatenating files.
