I'm not recommending this but Christian Bale put on the weight for American Hustle by drinking melted ice cream.
Honestly don't do it just to gain weight. Go to the gym, do weights, eat lots of protein is fine and I'd recommend anyone in their teens to do this as you set your natural bodyshape for the rest of your life but don't pile on fat to fill clothes. That'll happen as soon as you turn 20.

For home workouts, checkout programmes like insanity. They're not easy.
Otherwise look at "bodyweight fitness". If you can get a pull-up bar and/or a set of rings you'll be able to do everything. There's a good group about this on reddit Reddit's Bodyweight Fitness Community. That will show you lots of routines and youtube videos. You'll be doing dragon flares in no time.
