Playful punches from a girl, does it mean anything?

Yes! This is a classic flirting technique women use to show interest in a guy. If you tease a girl and she playfully hits your arm or shoulder, you know you've done your job right; it's a sign of affection especially if she smiled and giggled. It also means she enjoys your company and is comfortable enough to touch you in a playful way.
Yes, flirting.
When I do this with my male *friends* we do it to hurt. My buddy elbowed my butt right off his trunk and dislocated my shoulder when we were teens. “Sh-t are you okay?” “Uh, no a-s.” I only tapped him firmly. He had just waxed is car in some defense.
