will it be possible to set rights (view/edit/approval/publish/unpublish) for group of pages at one go.
I think it is possible to do at the page level, could it be possible to set rights for multiple pages at one go.
Could anyone please reply and provide the process to do multiple pages at one time?
Shouldn't be too much of a problem doing it with code. I wrote a short piece on mass updating access control lists for EPi6 some time ago, I guess it's not all that different in the newer versions. Have a look if it might help you out; here.
