There are a bunch of them between googolplexian and infinity. Here are the first few: googolplexian + 1 googolplexian + 2 googolplexian + 3 googolplexian + 4 googolplexian + 5 googolplexian + 6 . . googolplexian + 3 million . . etc. There are an infinite number of those.
Yes. After googolplex.
No. You can always add one to a number, to get a larger number.
There is no such number. In any case, you would not be able to distinguish it from a circle since there are far fewer atoms in the universe than the number of vertices that such a figure would have. I would settle for calling it a googolplexian-gon.

a googolplexian + 1
Yes. After googolplex.
Googolplexian has googolplexian zeros :)
That's not even a number.
Yes. Graham's number.
No. You can always add one to a number, to get a larger number.
A Googolplexian is the largest number with a name but otherwise numbers are infinite.
googolplexian and one. or perhaps googolplexian + Limx→∞ 1/x
to understand a googolplexian, you have to understand a googol and a googolplex. But a googolplexian is 10googolplex.
10^100 = one Googol
No infinity is smaller than googolplexian
