1. Can we create the users with different permissions in the project?
2. Can we restrict the users to view only the specific projects, not all the projects?
3. Do we have restrictions at the action level based on the roles?
If so, how can we do it?
See https://confluence.atlassian.com/display/JIRA/Managing+Project+Permissions and any recent questions here about permissions.
https://answers.atlassian.com/questions/83158/trying-to-restrict-user-access-to-a-particular-project - I asked a very similar question just in the last day or 2. This is what Nic is referring to.
