yes, you must delete the volume before removing a surface that bounds it.

I even tried to reconstruct volume 1 again by recreating all its surfaces again except 23, then use 40,58,68,78 as 
bounding surfaces to the volume but it did not work either. Is there away to join two volumes into one?

No

This may automatically ignore surface 23 during the mesh or allow its removal using the delete surface command. Please 
advise.

you will have to delete the volumes and the surfaces 23 , 40, 58 , 68 , 78 , and perhaps some lines, and then 
reconstruct "by hand" these lines and surfaces in a non-overlapping way

Dave
