Where did you come up with the amounts for the corn sugar?
The Mr beer recommendations are 3/4 tsp for 12 oz bottles and 2 1/2 tsp for 1 liter bottles. I think the Mr beer amounts are on the high side, but those recommendations are for white sugar. You used corn sugar, which is less fermentable.
Your beers aren't uncarbonated, just under carbonated. The larger bottles are probably okay.
You could try opening each bottle, add some sugar and recap, buy there are potential problems with that. For one thing, it's difficult to come up with the right amount to add. The beers have some carbonation, but they lose some when you open the bottle. Also, when you add sugar to beer, you provide a whole bunch of nucleation sites, so you get a lot of foaming. You can try it, but it may not work well. It may work just fine, but remember you'll be resetting the click on the carb phase.
One thing you can do is mix one of these with a beer that is more highly carbonated. I've done that in the past.
