"Then" is an adverb here. In this context, "then" is used to mean "also", "additionally", or "on top of that". "Then" used in this context is most common in spoken English as it is a bit informal and colloquial. Ex: I have three dogs, and then two cats. Ex: He makes money from his teaching job, and then he also gets paid from his part-time job.
