Projection angle confusion

I am little bit confused about projection angle A1 and A2, positive and negative sign is a chip on the shoulder for me. Anyone can explain which direction is positive and which is negative ....

In this case your space axis is X.
A1 Y/X - nominal angle is -0.1180°, actual -0.0878° is a positive direction or X rotates clockwise around Y axis
A2 Z/X - nominal angle is 0.4000°, actual 1.1727° is a positive direction or Z rotates clockwise around X axis

Easy way to visually see the direction of rotation would be to add 5° to either the A1 or A2 nominal angles and you will see the feature origin rotate.

if you get confused, you can manually enter the nominal value too high to see which direction it is turning on the screen.

The nominal should be 00.00, actually I never mind about nominal value in the feature menu, I correct it in my output characteristic area. The nominal value can affect the output result??

Yes. The nominal feature values are what determine where the machine moves to and what vector it approaches the feature at.

Ohh my goodness, I will keep an eye on it.But my machine moving in correct direction,I did not face any abnormality eventhough I did not correct the nominal value.

The nominal angles you have are pretty small so you probably wouldn't have notice much of a difference of the vector approaching the feature. You should still change them to zero.
