I am defenetly not Jedi224, and I hadn't heard of him until I read this. Jedi224 seems to have left googology on June 2018. Still, I think I can anwser your questions.

1-How big is [G,G,G,2](x). even though functions on the third part of the array are undefined, I think it works exactly like everything else. If I'm not wrong, this number is equal to the following: Call f0=G(x). Call f(n+1)=[G,fn,1,2](x). That function is ≈f((G(x))^(G(x)))

2-How big is [G,2,1,3](x). Undefined.

3-Why [f,1,b,2](x)=f(x). Because if not the rest would be undefined.
