In Jira ,Is there a way in Jira to see every project and project role that a user is assigned to? Clicking on the user profile does not give complete information.

Nope, it's useless. Knowing what roles people are in does not tell you anything about their access.
Think it through - "nic is in the role of cat-wrangler in project XYZ" - what can you tell me about my access to the project from that? Precisely nothing.
