Non-mahram approaching a group of ladies

Q: If a female is among a group of other females and a non mahram male approaches the group of females to speak to the other females she is in the group with, is it enough for this particular female to lower her gaze and refrain from useless chatter with the male while still standing in the group or is she supposed to leave the gathering when the male approaches?

Enquiring about the Deen of the girl

Q: My parents are searching for girls for my marriage and when I go to see any girl along with parents I keep on asking them about Deen, Islam, namaaz, Quran recitation and how important is deen to them, all these sort of questions. They give proper reply as well but they are rejecting the match saying that I am very strict or how can I ask such questions as they too are born Muslims. I ask these questions not to check how pious they are or I am not saying that I am perfect, just I am looking for some one who knows Islam well and who can correct me as I am not perfect. So my question is is it wrong to enquire a Muslim girl how much she follows or knows deen?
