I bet that if you can improve your posture you could grow an inch. I say this because teenagers generally have poor posture and slouch.
While it's unlikely you will physically grow more than 1cm over the next couple of years, it depends on how far into puberty you are. If you were a late bloomer then you could grow a lot more over the next year or two! However if you were fairly average then you probably will have finished the part of puberty which makes you have growth spurts. :/
EDIT: I'm male, and was 5'7" by the time I was 12. However, I stopped growing when I was 16 and am about 5'7"-5'8" now (depends on who measures me...) so I sympathise as I am also shorter than a lot of my family. My brothers and dad are 6'+ and my older sister is 5'10", so I definitely feel like a shorty compared to them!
