Gallimore's hit on Devito: It looks like a momentum hit, at the waist. It was a bit late, could have been redirected to avoid the hit altogether, I think.
Pugh's reaction: He hit Gallimore out of frustration, in the moment. It looked like a ground and pound in UFC.
Gallimore's hit on Pugh: Contact was made at the waist, a reflex with his leg to prevent further attacks while laying on the ground. The heel did contact the groin area. I don't think there should be a fine for this, preventing a ground and pound. Pugh was taking a risk by attacking a player on the ground.
If Gallimore gets fined, so should Pugh.
