What are the right ascension and declination of the star alderbaran in the constellation Taurus?
According to Wikipedia: Right ascension 04h 35m 55.239s, declination +16° 30′ 33.49″. The data corresponds to the epoch 2000.0.

Using declination and right ascension
Does earth's revolution around the sun change both the right ascension and the declination of a star?
yes
How do you measure the location of a star?
Using a method similar to latitude and longitude on the surface of the earth. The corresponding terms are declination and right ascension.

The closest terrestrial analog to hours of right ascension is angle of longitude?
yes. latitude is to declination, as longitude is to right ascension.
What are the right ascension and declination of the star alderbaran in the constellation Taurus?
According to Wikipedia: Right ascension 04h 35m 55.239s, declination +16° 30′ 33.49″. The data corresponds to the epoch 2000.0.
One hour of right ascension is equivalent to how many degrees of sky rotation?
Depends on the declination in question. There are 24 hours of right ascension in 360 degrees, so at the celestial equator (declination = 0 degrees) 1 hour of right ascension is equal to 15 degrees. But as you increase or decrease declination the right ascension lines converge to the celestial pole (like longitude lines on a globe). The angle covered by 1 hour of right ascension is therefore equal to (15 degrees x cos(declination) ), so at the celestial poles (declination = +/- 90 degrees) 1 hour of RA is 0 degrees.
