Thank you for asking!
Xyrm are being transferred all around the Universe, so yes they can appear anywhere, not just on Earth, and even in other ARPGs.
Placements are determined on Percentages (EX they will have a 50% chance to not fail). So if you make a placement piece, the quality doesn't matter, the stats of the Xyrm are what matter ;3, Of course, you have to train them first and have a placement chosen for them. As the xyrm's SP rises, they can enter more placements as well. you can sign them up for multiple it is just only one can be active at a time!
For Breeding you will need 2 slots, one to a male and one to a female, both need to be trained and have a breeding certificate.
You will also need a Host egg(s), available in The Emperor's Shop. Then you are ready to breed.
