You can "submit" modified assets (ie. files and/or folders that have been created, updated and/or deleted) from the author sandbox to the staging sandbox. You can also optionally configure the submit to go via an (review & approve) workflow sandbox.
As per the sandbox concept in WCM, any contents/items created in user sandbox will not be directly available in staging sandbox.
User will have to submit the contents to the staging sandbox in order to make them available in staging sandbox so as other users can also see the contents/item created by this user.
There is also an option to configure a workflow for approval before submitting the content from user sandbox to staging sandbox in order to ensure that only the approved contents can go to the staging sandbox.
