Apples on the tree is correct. Actually, both birds in the tree and birds on the tree both work. For example, "Do you see those birds playing in the tree?" "Do you see those birds hanging out on that tree?" Punch me in the face is correct. We never say, "he got punched on the face." Both dirt in the face and on the face work. For example, "You have some dirt on your face. Get a towel and wipe it off." To show the other one works, you can say, "The wind blew dirt in my face."
