1. How to train triceps with powerball?

Keep your arm almost straight, and most hand positions will train the triceps. However, I also once found that rotating my right hand anti-clockwise, with my hand up near my right ear, palm facing my head, targetted my triceps nicely.

2. How long do you train and what muscles per day?

To start with about 5 or 10 minutes a day would be plenty. In time, 30 minutes or an hour at a time is a really good workout, but don't do too much too soon or you could injure yourself.

3. What muscles are needed for throwing a ball?

I would say shoulders and triceps, but also pectorals.

One more question: What muscles I should train with PB to get better on pull-ups, not chin-ups

[XTTX]

It depends which grip you use for pull-ups, but generally (most of the time) you will be working your biceps.
