Yes. The XTi and all the EOS cameras take the EF lenses. However the EF-s lenses that will work on the crop sensor of the XTi will not work on the Rebel G or other "full frame" camera like the 5D or the 1D series.
Yes, any EF-mount lens will work fine on the XTi (EF-S mount). However, because the APS-C sensor in the XTi is smaller than a frame of 35mm film, there's a 1.6x crop factor. This means that the 28-80mm lens will have an equivalent field of view of a 44.8-128mm lens.
Yes. Any EF Series lens will work on any EOS camera. If you use the lens on a APS-C format camera (commonly called a "crop camera"), the apparent field of view will be smaller. Your 28-80 lens will now be the equivalent field of view of a 45-128mm when used on your EOS Rebel G.
Think of it this way:
Lets say you had a Rebel G and a Rebel XTi.
Set up a tripod, and put the Rebel XTi with the 28-80 on it. Change the focal length to 28mm. Take a picture of anything, a building, a tree, a barn, it does not matter.
Now setup the Rebel G (or any full-frame DSLR like a 5D) in the exact same way, with the same exact subject, but this time set the 28-90 at 45mm.
If you were to compare the photos, you would basically have identical images. The field of view would be the same, so you would be seeing the same amount of "stuff" in each image.
