Problem - I have stopped growing about 2-3 years ago(currently 17guy) Is it still possible to grow?

At age 14 you were close to 90% of adult height, and 95% at age 17. So you probably will grow another inch and a half. After that there are just two ways to make yourself taller:
1. Put lifts in your shoes.
2. Put a box on your head. i.imgur.com/9kXJc.jpg
