Answer 1

The common pattern for scenarios like this is to have a Logic App for each Trigger/Topic/Subscription.

Then these Logic Apps, two in your case, call a third work Logic App which does any real message processing.

Answer 2

You can use the Event Grid trigger if you have Service Bus premium, to subscribe to Microsoft.ServiceBus.ActiveMessagesAvailableWithNoListeners event. Once the Logic App is triggered, you can then use the Service Bus action to retrieve the actual message and process it.
