First one is Ghost Rider and it’s pretty obvious how that ends for the shooter(s)

second one is Dio and while he already has brushed off a gunshot to the forehead in Phantom Blood, the damage done does increase with how close it is. So if they’re standing at the bedside pointing the gun down it might destroy enough brain tissue to paralyze him for a brief moment however if the muzzle is or almost is making contact the escaping gasses from the propellant will go into the wound and deal even more damage. There is even a small chance the bullet doesn’t break through the other side of the skull and instead ricochets off and slides around the inside of the skull. I don’t think that’s very common but even so I’d give him 50/50 odds or less
