No, but its necessary closer

The appearance of a star in earth depends upon many factors like its distance from earth, dust particles and other obstacles lying between the star and the earth,scattering of its light in the atmosphere of earth etc.So it is not necessary that if a star appears brighter it is necessarily brighter.

Not necessarily. It depends on the distance of the star from the observer. If the distance is greater, even if it is brighter than the other star, the first star will not look that bright.

It would certainly APPEAR brighter but that just might mean it is closer. The further star might still be putting out more energy.
There is a difference between APPARENT brightness and ABSOLUTE brightness.
(Absolute brightness is the apparent brightness of the object if it was 10 parsecs away from us)

If it is brighter then it is brighter, if it appears to be brighter, that is a different thing.

There are two concepts involved, intrinsic brightness and apparent brightness. Apparent brightness is what you see. Intrinsic brightness is what you WOULD see if both stars were same distance from us. So your answer, based on the two criteria above, could be either yes or no.
