Red shift occurs when an object moves away from the observer. So as you are on Earth, it is when objects move away from Earth. (Blue shift as it moves closer.)
A star's red shift could be due to losing energy to gravity.
No. A redshift means that the light has lost energy; one way for this to happens is if galaxies or other objects moveaway from us.
No. A red shift indicates that the object is moving away from the earth.
They are not actually, moving, they just appear to be moving because we are. Consider that if you are on a train moving forward, objects that you pass by appear to move toward the read of the train.
Gravity
yes gravity pulls object toward the earth Here on Earth, the force of gravity does indeed pull objects down toward the Earth. But bear in mind that gravity is a universal force. On the planet Mars, for example, gravity pulls objects toward Mars. All objects in the universe have their own gravitational force, the strength of which depends upon how massive the object is. The sun is much heavier than the Earth, and the gravitational attraction of the sun is enormously greater than that of the Earth.

Increasing wavelength is an indication of a Doppler shift caused by an object moving away from the viewer. Longer wavelengths (of the visible spectrum) are redder, shorter wavelengths are bluer. Objects moving away from you have a red shift, objects moving toward you have a blue shift.
