Sorry, he's just a priest now. A priest with incredibly poor judgement and fortitude, who has a lot to feel guilty about for abandoning his duties.
There is no such thing as “Pope Emeritus” in Catholicism.

Yes. No. Yes.
Pope Benedict resigned his “active ministry”, he did not abdicate. True, there is no such thing as Pope Emeritus, that is part of his mistake. He had to fully resign or he is still Pope.
