I refilled the coolant and began to check for slow leaks under the car over the next week. Found a few puddles here and there and decided to bring my car in for a pressure test.
Coolant started leaking right out of the block! on either side, out of the "freeze plugs" something I had never heard of before.
It seems like the freeze plugs are NOT part of regular maintenance because there are 16 of them and the engine needs to be taken out to get to the things.
I'm wondering if anyone has any insight on this, I'm heartbroken over this job and looking for clarity.
Is it okay to replace the easily accessible freeze plugs? or would that cause the others to leak more?

If the freeze plugs have started leaking then you need to replace all of them. There is no way to tell what condition the non-leaking ones are in, and considering all the freeze plugs see similar conditions it's very likely that the other ones will start leaking soon. Since you have to remove the engine to replace the freeze plugs I would check your engine compression to verify you didn't cause any damage when it overheated. It would be a bummer to pull the engine to replace the freeze plugs only to discover that you cracked/warped a head or have a bad head gasket from overheating. If the compression checks out and you decide to pull the engine that would be a good time to reseal the engine and replace all the oil cooler seals/hoses as well.
