She is paying attention to the/her ring. She is paying careful/close attention to the/her ring. With “paying attention” you don’t need “her”. With other verbs you would. “She is focusing all her attention on the ring.” “She is focusing all of her attention on the ring” “She is giving her attention to the teacher”

1. Yes, you can use that in present continuous, especially if it’s used in something like, “While I’m waiting for her answer, she’s paying all her attention to the ring.” 2. You are correct.
