@adrianoresende asked "When I add some report on dashboard, display a list a lot saved reports, so how I delete some saved reports?"
Answer from @sarah.horton "Hi @adrianoresende, it sounds like you want to delete a Dashboard? If so, this Community post might be helpful for you https://community.mixpanel.com/questions/208/how-can-i-delete-a-dashboard.html
If you want to delete a regular report from Insights or Funnels, you have to go to the saved report, hover over it, and click on the trashcan icon next to it to delete it. Hope this helps you out! :-)"
