If Simon's ability has activated and he discarded, then healed, would his ability remain activated?

Is he CBI after the phase he is activated in?

For the first, it should return; he's basically returned to the exact same state as he was in before leaving the field.

For the second, the "while in play" part has completed, and is therefore CBI; the protection is ongoing and has not completed, and therefore can be negated each phase.

So if the negation was removed, would it reactive with the same target?

Any ongoing ability that is negated or prevented turns back on once that source is undone, yes.
