Sure you can play, there are different positions on the team, sometimes they need a husky tough guy who can stand his ground but they also need guys who can run fast and run around and between other guys. Some of the big husky guys aren't as fast or nimble.
Yeah, bulk up a bit and play 13, 14 or 15.

Yes. I am 5'4 and 130 pounds and play rugby
Absolutely mate. Obviously it's difficult without knowing your attributes skill wise but judging off your build, I don't see why you can't play on the wing if you have a bit of speed. As with everything else, you will get out what you put in.
