There is none
A googolplexian is an incredibly large number, specifically 10^(10^(10^100)). Numbers larger than a googolplexian can be represented in various ways, such as googolplexian + 1 or by using mathematical notation like "googolplexian squared." However, there is no standard term for the next specific number after a googolplexian, as the naming conventions for extremely large numbers become less formal and more arbitrary beyond certain points.
Yes. Graham's number.

One googol = 10100 One googolplex = 10googol One googolplexian = 10googolplex so 1 googolplexian has 10,000 0's after it
a googolplexian + 1
The larger exponential is represented by "googolplexplex" (etc.) or "googolplexian".There are vastly larger numbers, such as "Skewes' number", "Moser's number" and "Graham's number" which can only be represented by large power towers of exponential exponents.(see related question)
Hundred googolplexian and one! There is no end to the list of integers; we don't have names for very large numbers - practically, there are very approximately 1040 atoms in the universe - less than half a google - so there isn't much call for very large numbers outside of mathematics.
Quadrillion,Quintillion,sextillion,sentillion, octillion, nonillion, decillion, and infinity!
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.
Googolplexian has googolplexian zeros :)
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.
