I assume anyone with artificial bone implants would ask a doctor to remove implant before rejuv.
If not, the bone implant would be pushed aside by the regenerated bone. The implant then would damage surrounding tissue. The rejuv would again push aside the implant until it was finally forced out of the body.

Same as above.

Both, the default is "all or nothing". It can be as selective as needed.

That is optimal. However, rejuv would just remove the implant.
However, there are Boob Enlargement Labs that can turn your slavegirl into a big titted bimbo by injecting her breasts with IV solutions to grow giant, massive mammaries.
