Castiel needed to focus to blast open a normal door, that requires ruthly the power of a 1000Kg  car driving 100Km/h. Non relativistic kinetic energy is calculated by W = 1/2*m*v², where m is the mass of the object and v is the speed in m/s

100Km/h are 28m/s, rounded. Makes W = 1/2 *1000Kg * (28m/s)^2 = 392000J. As Cas needed up to 7s to build that blast up, we have a power P = W/ t = 392000J/7s = 56000W.

So, that should be the energy an average angel can produce in a second.

On the other hand with have the energy output of a galaxy per second: 386000000000000000000000000000000000W.

Means, if the Host of Heaven can produce the same power energy like the milky way in a second, there a  n = 386000000000000000000000000000000000W/ 56000W =  689285714285714285714285714 Angels.
