Yes, I actually don't care about physical correctness in a fictional universe, and neither should the writers. For that reason I think attemps to quantify any character are rather pointless, it has by no means have to follow any physical law. They could decide to make humans so strong that they could lift the moon but unable to lift a car. Sounds illogical ? It isn't since it only violates the laws of physic, not the laws of fundamental logic. The logical possibility of the above situation could be proved with a simple simulation.

Well but anyway, some suggestions:


 * Raphael caused a lighning storm, you could make some assumptions about it's size and the frequency of lighning, the power of the wind, ...


 * Michael burned an angel to ash with a simple touch.


 * Lucifer's true form enlightened a whole city. You could make assumptions about the intensity of the light as well it's energy.

... basically there most impressive feats are reality warping and time travel. That's hard to quantify, especially sine time travel to the past requires unimaginable amounts of energy. Therefore it's safer to say that they just override the physical law itself to make it easier.
