I think international arrivals still come in at Terminal 5. So you have to do the immigration/baggage/customs/baggage-recheck thing there. Then to get to Terminal 1 (where most UA departures, domestic and international, are), you would have to take the train. Terminal 1 is the last terminal you hit on the train. There is a chance your flight would be from Terminal 2, which is one stop sooner. Then through security (queues are long sometimes), and depending on what gate your flight is from, it might be a short walk, or a fairly long walk through an underground tunnel, possibly followed by another moderately long walk through the terminal.

It is possible to make it in 92 minutes, but it is also possible not to If it is extremely important for you to make the final destination on time, I'd be at least a little worried.
