You don't need to specifically say my name, all the users are free to answer the questions here. Well off to your question.

Yes Kuroka still has her Evil Pieces with her thus the Stray Devil term is used not only for her but many others too. We don't even know if it's possible for the Evil Pieces to leave the body of the Reincarnated Devil, but seeing Azazel's reaction when he saw Issei's Pawn Pieces in Volume 11, having the Evil Pieces leave the body probably would result in death.
