After my first win my blitz rating suddenly increased by 150... Whats happening
The first games the rating goes very much up and down, after more games it will stabilize.

Ratings on chess.com do not have to be very accurate.
My very low rating of 1658 for Live Bullet is not accurate at all
AS I HAVE NEVER PLAYED A BULLET GAME IN MY LIFE!!
Well somebody on your account has won 5 games of bullet. You played them about 5 years ago

I have 1000 rating discrepency between different parts of chess. How could this happen to me?
Your surname could be a clue.

turtle, the general points system followed is as follows:
pawn - 1pt.
knight/bishop - 3pts.
rook - 5pts.
queen - 10pts.
of course points are not everything... the position of your piece also matters.. for example you might not mind losing a bishop or rook to save a pawn on the 7th row.. and points dont have any bearing on the game result.. it is just a basic framework to help beginners understand the value of different pieces
Pretty high rating for someone who doesn't know that a queen is 9 points.
2 rooks + pawns can usually beat Q + pawns with same # of pawns
rating of player are right but if you get better very fast at the game rating dont go up fast
