3. Finally, can you share some neat implementations of 3 position cylinders on FRC robots?

You would plumb it just like any other actuator. What the rule is stating is that two solenoids cannot have their outputs merged to feed one actuator port. The simplest explanation I can think of at this time is to use 3 single-acting solenoids on a common manifold. You can use double-acting solenoids as well.
