Character #1
As Plastic Man, head to the place where Green Lantern is.
The place that you can see in the picture is where you can unlock The Atom. Destroy all the silver objects and build a machine from the bricks. You can use Cyborg's Demolition Suit to smash the items.
After completing the previous task, go left and put out the fire using Batman's Arctic Suit. Use the hook to lower the lever located higher.
Go left and use the vehicle located there. Aim at the machine that you've built (if you have troubles moving the camera, just press the key responsible for looking down). When driving, clean the green substance from the floor.
After aiming at the machine, the vehicle will land automatically. Get out and use the levers that show up. When you use both of them, you will be able to access The Atom Character Token.
Character #2
The second character can be obtained by hacking the terminal located in the right part of the room. After doing that, a box with an item inside will show up. Take it and go to Bat-Mite, who is standing in the middle of the room. As a reward, you will obtain Beast Boy.
Character #3
In the room with water containers, go to the right side and use Robin's Magnet Suit to access the box. When it falls down, switch to Batman and wear Sonar Suit to smash the glass barrier. After picking up the Token, you will unlock Stargirl.
