is it muttar for a ben torah to have a coversation with his female cousins?

By the the evry fact you ask about a “Ben Torah” vs. a normal Jew, you are asking about societal norms, not Halacha. As such, the answer is no. What if someone sees you and thinks you are a Mushchis, CV? You may be Passuled from life support!!
Stay away.
