Annotating text with multiple labels simultaneously

Can I use Prodigy to apply different labels to different spans of the document I am viewing and annotating?

E.g. "Merk is a pharmaceutical company with revenues of $x and profits that exceeded $y. The CEO of the company John Smith presented his new plans for restructuring the company is the Board meeting that took place in 2020/02/10"

I might want to apply several labels in the short document for the following tokens: 'Merk', 'pharmaceutical', 'x', 'y', 'John Smith', '2020/02/10'.

Would that be possible?

Sure, that's no problem and a pretty common use case for NER annotation. In case you haven't seen it yet, the NER documentation has a bunch of examples of the different workflows and interfaces:
