What you need for your load testing is to use Immediately Ramp in your Staging Document for the Load Pattern Selection.
As per the documentation:
Immediately Ramp
The Immediately Ramp pattern applies when you are running only a few virtual users (instances) but you want to specify the test duration. You are not concerned with any loading pattern. This pattern starts all virtual users simultaneously.
To configure this pattern, enter the following parameters:
Instances
The number of virtual users.
Max Run Time
Select either No Max (the test case determines the time) or Maximum Run Time. In the latter case, specify the Maximum Run Time. This setting overwrites any value that is entered for Cycles. You can specify h for hours, m for minutes, s (or no letter) for seconds (default).
So if you choose Instances of 2 and a Maximum Run Time of 5m (5 minutes), it will show 2 virtual users on the Reporting Dashboard, this will run for 5 minutes and it will also show how many Cycles executed for each virtual user. When your Suite finishes, go to the DevTest Console and choose Reporting. Then click the Grid checkbox true on the upper right side of the page. Then double-click your Suite, it will show the test case. Double-click on the test case to see the detail.
