@Amrinder , You can control the user access to the projects in the roles section of the project.

Restrict the other 9 projects to certain users directly mentioned in the roles configuration of the projects.

If you want this one particular project to be accessible by all logged in users (even the future new onse) , you can grant the access to jira-users group.
