how to make advance level test planning (scripting) with scenario

I want to do testing according to following scenarios.

1) I want to ramp up users login to my application from 1 to 25 users in increments of 5 every 2 minutes. (I have achieved this through concurrency thread group)

2) Once we reach 50 users, have 5 users expanding defect donut and 10 users expanding release quadrant, 5 users clicking on defect details and 5 users logout.

Please help me to achieve this.
