5'7 thats pretty good height

Just listing your age and currant height is nowhere near enough information to make a guesstimate on any potential growth you may experience. You should consult your doctor for a more informed answer.
However, generally speaking... males usually complete the physical side of puberty somewhere around 18-21 years old. So there is a possibility that you could grow, but without knowing all the facts about your personal situation, there's no way to accurately predict "if and when".

I grew about 2 inches between 18 and 23, so it can happen. I was always on the short side, and had pretty much gotten used to it, and then I noticed that I was average height and even a bit taller than some of friends (that I had always been slightly shorter than).

Anything is possible - but no guarantee's. You still have at least 3 more years of puberty left. Some guys continue to grow right up until puberty ends. Don't worry about stuff you have no control over. Life is not always the way it's supposed to be. It's just the way it is. The way you cope with it is what makes the difference.

Anything is possible, I was 5'7 for the longest time, and I will be 18 in about a month and a half and all of the sudden I'm 5'9.

probably not
