For Part 2, if my assignment's business domain model shows some business entities that never appear in any of the use case specifications, do I need to add this kind of business entities to my class, component and sequence diagrams?
For example, if the business domain model has a "Payment" class, but "Payment" is not mentioned in any of the use case specifications, do I need to do anything with "Payment" for my diagrams?
Thanks in advance.

It's hard to say. It seems likely that you do need to include it and it is implied in the use cases. But it is possible to be just background knowledge.
The most important thing is to be able to justify your decision either way.
