Yes, Deffinitely you can. But it is depend on you. How much you can observe and learn. Keep learning and express yourself around your friends and colleague :)

Both are correct. But in speaking "he is abroad" is correct.

We can use "you" as 'tum','tu','aap' etc. e.g : You are great. You know me. Who are you ? In other words, Hindi is a very decent lang where we use lot of words to express tu, tum, aap etc.
