On some steam excursions, a diesel is sometimes added. My question is how do the engineers in their respective locos know how much throttle & brake to apply during such runs? Thanks for any info on this process.

The throttles are controlled separately by their engineers. Coordination can be through whistle signals or radio communication. The braking control of one of the locomotives is slaved to the control of the other, so one engineer will control the braking.
Some excursions that regularly use a diesel helper have added a control stand to the steamer and MU that to the diesel following. Especially when the trailing unit is a B unit painted to look like a baggage car. The engineer has 2 throttles to operate, but it is just 1 engineer.
The old Clinchfield #1 was set up that way.
