Contains 3 characters, including my old Porl character (but refined a tad bit and dressed).
Press N to open up all the UI options. The foot roll, finger rolls and face controls are all there using sliders, just select the right bones to see them. The IK/FK, stretch controls and layers are always there though. If you want to keyframe one of the sliders just hover your mouse over it and press I to insert a keyframe.
If you want to add your own clothing, just delete all the clothing parts, select the main mesh and remove the mask modifier to reveal the whole body.
The rigs are all the same and consistent too, have fun.
Also, make sure your Armature name is always Porl_Rig or Ed_Rig or Elaine_Rig depending on what character you're using, or else you won't see all the UI controls. If you're planning to link the characters into a scene and then making a proxy for the armature, it'll remove the _Rig part and add _Proxy so make sure to rename it.
