I cant execute apps from the terminal draggin them

Why do you think this will start the application? A .app "file" is really a folder containing the application code and all it's resources. When you drag a folder to the Terminal it put's that folders path in the topmost terminal window. This is the expected behaviour.

 

To make this work in terminal, you need to use the open command. So, type open -a (followed by a space) and drag in your application bundle, so you have something like open -a /Applications/Stickies.app/
