Congrats on your first rebloom.
I know how exciting that is!
With the way your spike and the buds are, I don't think it will make many more buds at this time.
You have two buds for sure and the tip looks like it will elongate some more.
Many mini phals do that that. They either explode at one time like the larger varieties, or just a few here and there but for a long long time.
So either way, you will enjoy the bloom.
I have a super mini phal (I think it has a equestris in it) I bought at a supermarket back in the winter. It came with about 5-6 flowers open.
After it dropped all those flowers, it kept on adding two three new flowers.
The tiny plant (barely 7cm across) is still in bloom with two flowers ( barely 2cm wide) and two buds coming.
