I believe I have some trouble understanding your request. From what I can gather you have a list of links to either pages or content items. Should the page give access to everyone these links should be visible to all users.
If you want to restrict the items the links point to, you are able to do so by setting appropriate permissions
to these items. If a user has insufficient permissions to access the item, you can redirect them to a custom login page as described here
