Hello,

Do stars rotate? I mean to say that do they rotate in angular momentum? Or there is any other rotation?

Yes, stars rotate due to angular momentum acquired from gravitational collapse during their protostar phase.

Rotation of star

Hello,

Thanks. I believe pro star is the earlier stage of star formation. What happens when the star if finally formed? Does it have a angular momentum then also?

The star we know best, our sun, is "finally formed" and it rotates. According to wikipedia, http://en.wikipedia.org/wiki/Solar_rotation
its equator makes one rotation in about 24 and a half days. Of course, because it is gaseous, different parts, at different latitudes, can rotate at different rates.
