When you say different queues, I assume you mean issues/requests in a queue not tasks/approvals. You can make an issue report, filter only to project names that are the queues, and filter to incomplete status, and then group the issues by project name. Will give you an easy view of active/incomplete issues in queue projects.
If you mean incomplete tasks in projects, you can do the same thing but with a task report and filter in XYZ projects you're looking at.
If this helped you, please mark correct to help others : )
