In terms of proper driveshaft angle, there relative to one another, in relation to output/input ends of the shaft.
For single carden ujoint setups, like our rear driveshafts, the rear axle pinion end should be equal or 1* less than the tcase output angle.
For double carden, or CV ujoint setups, the rear axle pinion angle should be zero, as in points right at the CV setup, the pinion yoke having the same angle as the driveshaft.
If you Google ujoint angles, there's aton of links and articles about angles, setups, and pictures.
For maximum angles, all depends on your size of joint, but usually they last longer if the angles aren't as severe. Wish I could remember where I saw it, but Spicer had a chart that listed different ujoints and there life expectancy at different angles
