Boulder diameter: 111 pixels or 2.37m, radius is 1.185m
Volume (assuming sphere): 6.97 m^3 (actually more since I didn't account for the spikey bits)
Fragmentation: 8j/cc
Violent frag (there's a lot of dust formed): 69j/cc
Low end: 5.576e7 Joules or 0,01333 Tons of TNT

Or to be more specific he grabs the gun and bends it in a different direction to divert the shot b4 it leaves the barrel, only beggining to move after it fires.

Lao Gui is from china so this is fairly likely to be the firearm.
Barrel lenght: 95mm or 0.095m
Muzzle velocity: 274m/s
Timeframe: 3.467e-4 seconds
Goro Majima is:1.86m tall
And he seems to have raised his arm past his head so:

Goro: 1199.4 pixels
Palm to head vertical distance: 706 pixels or 1.095m
Speed: 1.095/3.467e-4= 3158.3m/s or Mach 9.3

Kazuma wasn't quite at the epicenter, but the scaled explosion is from outside the building and he was in the rubble and everyone that wasn't Nishiki was fine afterwards, so it's something.
KLOL506's version[]
I figured out the distance Kiryu was away from the explosion.
Kiryu (red) starts at 81px and ends at 326px, giving us 245px.
Kiryu is 184 cm tall.
184cm= 245px
The blue line (Kiryu's distance from the epicenter of the explosion) starts at 1033px and ends at 633px, giving us 400px.
400/245= 300.40816326530612244897959183673 cm
AKA Kiryu was 3.004082 meters away from the explosion.
P= 1.24 tons of TNT.
Kiryu is 3.004082 m away from the explosion, so we use that as the radius.
R= 3.004082 m
I= (Yield of actual explosion) / 4π((distance kiryu was away from the explosion)^2)
I= (1.24) / 4π((3.004082)^2)= 0.01093423125895362288540172863626 tons of TNT (Small Building level).
CA= 0.68 m^2 for a human
Therefore, 0.01093423125895362288540172863626 tons of TNT/m^2 * 0.68 m^2= 0.00743527725608846356207317547266 tons of TNT (Small Building level).
Yeah, 9-A is consistent for Kiryu. Also, the normal frag end is fine, since large pieces are all over. Violent frag would apply if the fragments are considerably smaller.
