Voltage and CCA would be fine, however you may not have room physically to fit the the Hyundai battery in the Honda civic; you may also find that the terminals are on the opposite sides.
A better solution would be to take the Civic battery, put it in the trunk of the Hyundai, and take it to a car parts supplier. They will be able to test it for you. If it's OK, but just discharged, they'll usually charge it for you overnight for free. Once you get the Honda running, take it back to the same store, and they'll do a comprehensive charging system check for you.
You could also (as an alternative) try to jump-start the Honda from the Hyundai. Once it's running, drive to the car parts supplier for a diagnostic test.
The only downside of the above is, what will you do if they tell you that the battery is OK, but the alternator needs replacing? They'll sell you an alternator, but they won't fit it for you.
