There is no public API to retrieve the list of tokens that are subscribed to a topic. If you want such a list, you'll have to maintain it yourself.

Can I subscribe a topic to another topic? – Thejas Kumar Feb 06 '19 at 06:17
No. But you can send a single message to multiple topics with conditions, which probably accomplishes what you need. See https://firebase.google.com/docs/cloud-messaging/send-message#send_messages_to_topics – Frank van Puffelen Feb 06 '19 at 15:04
