1. The first crucifix
I would print it vertically, but I'd tilt it back about 30 - 45 degrees, AND tilt it to the left (or right) 30-40 degrees. You'd then only have two supports to add to it.
2. The 2nd crucifix.
This is one more challenging, as you have ornamental work all over the place. I would remove the bail and print it separately. I'd then flip the crucifix 180 degrees (and tilt it sideways as in #1) and support it from the location where the bail was. You'll also have to support the lower arm of the crucifix.
3. The pendants
The reeded edges make printing these a bit more difficult. I'd attempt to support them at the little balls on the face of the pendant with small supports. And one on the lower edge. Then I'd say a little prayer to Chuck Hull and hope for the best.
