1/ Yes, someone tried the original adapters from the stock Gshock square and it worked. Keep in mind that you might also need two regular spring bars since the GM-2100 uses quick-release bars

2/ you can also buy this:

3/ I don't have this G

4/ It has been along time since I cared to measure the nato strap that fits into the stock Gshock adapters. I think it is 22mm and sometimes 24mm. I always prefer the wider the better to be the same wide as the bezel's size or wider

So long ...

Well, I tried to get some help recently and I was trolled for asking a simple and legetimate question.

You are right, some members are very disappointing on this sub-forum. While I still think most of them are well intentioned.
