While the MacBook Air is not capable of outputting to more than one external display natively, you should be able to add a second display by using a USB Graphics adapter. You can pick those up from most online electronics retailers and they are relatively inexpensive. Make certain that the one you select indicates it is compatible with macOS.
How do I connect more than one display to the MacBook Air?
