How do I use touch to move stuff?

I tried this https://www.4shared.com/file/J7JByyT5ei/inputtouch.html
but there are 2 problems: 1) all the instances of the family move while I want only the one I touched to move
2) the movement don't go from point A to B but it keeps moving indefinitely.

Here's one way to do it:

add a Boolean variable to the object you want moved, make it so when the mouse clicks on the object, it sets the Boolean to true, then add add physics to it, make gravity be set at 0 at the beginning, set friction zero then after that you can apply force to the sprite towards the mouse.
