The condition of the elements that are <not associated> and ones that are orphaned is the same in that they are missing their hosts. When face hosted elements lose their host which is in the project, they become <not associated>, when elements are hosted to objects (usually linked files) that get deleted, they become orphaned.
Using the "graphics" button in the Reconcile Hosting dialog will allow you to change the color of "orphaned" elements, but not ones that are <not associated>. The only way to rehost elements is one-by-one.
