Hello Markeymark, and welcome! Your plant is actually two plants put together in one pot. They are healthy Phalaenopsis orchids. There is a long thread about caring for this genus, which I suggest you browse:
The Phal abuse ends here.
It is normal for flowers to drop after plants are moved or just after some time. You have no way of knowing how long it has been in bloom, but phal blooms do last a long time, months occasionally if they are happy. So enjoy them while they last, and then be prepared to repot (and separate) the plants and provide the best culture you can, so you will get more blooms to enjoy!
