Hide menu backend side for different roles/users
You can use Menu item visibility module to hide the item for specific user role.


  This module exposes configurable and extendable visibility settings
  for menu links. For example, if you want to create a 'My account' link
  that points to /user, both anonymous and registered users have access
  to the /user path, so both will see the link, even if anonymous users
  do not technically have an account. Using this module will allow you
  to only have your 'My account' link visible to registered users, and
  hide it from anonymous users.
