Hello Seika85, please read more about all types & value of attack you can train at Train Robot Dragon, you will find infomation there For your questions:
 * 1) Can you re-teach an electric attack: No, sorry you can. Because the train has no electric attack, so you can teach any electric. Furthur, after your training done, that new ability still remain there as an option in the training center, but this time it is disabled (grey, unclickable). So once you train, new attack will stay forever.
 * 2) Can you sell and get/buy another Robot Dragon: No. Robot Dragon is GEN EX, that means you can breed or buy. You probably got it from playing Social Wars, therefor you can't get it twice.
 * 3) Can you cancel training. I think no, only way is to insta-done it buy using gem, which is silly if you want to cancel...

I hope my answers are clearly for you (English is not my tongue)
