Can any one suggest me how can i move the turtle as in the real mario game series

You'll first have to code the sprite of your turtle and not use the levels with the turtle on it then switch to the level sprite without the turtle after collision. Place your turtle sprite the same method you placed your level sprites. scrollX + location.

You can then set your conditions for the collision with your controlled sprite. Assume the turtle has 2 costumes, one with head out (costume1) and one with head in (costume2). If touching the controlled sprite and costume # = 1, set gravity to 5 (to make your guy bump), switch to costume2. If touching controlled sprite and costume # = 2, set gravity to 5, point it in the direction of the main sprite and repeat moving until you touch the edge.

Edit:
I made this project a few years ago that has examples of different Mario enemy types in a scrolling world. This will help with the movement.

Thank you very much

Good luck on your project. I did make a remix of your with what you were asking. If you get stuck let me know and I will share it.

Of course

I have tried it out but it stops at the edge. (Does not go out of the screen)
How to do it??

Here is the remix. I am away from my laptop so I can't see your scripts. I will look when I get back.
