Can one use taqiyyah and not fast the Month of Ramadhan? I just learned a friend of mine is being hit (and bruised) by their parents for fasting, can they refrain from fasting and use taqiyyah?

If it’s to protect their life and well being then yes. However, this person should see if they can get away from their parents and go to a safe place. It’s not good to stay with them when they are being abusive like this.
