Answer 1

It sounds like a shoot from the original rootstock (Which will almost never be the same as the top graft) has grow out and fruited!

As long as it is not affecting the health of the Calamondin, then it will be ok to leave it. If you start to notice it taking over the tree, then you may want to cut that branch out at the base.
