Usually they get two to four names. There is no real limit though. Not all
domain names create huge bundles and even if they do, how many would a user
choose to pay for and for what benefit?

Your examples are not valid, they are the same domain name. The upper case
to lower case conversion does not produce different domain names, even in
IDN. However, if you have a letter with tonos there, the user would type
this word in capital letters without tonos and this would be a different
name in PUNYCODE.

Usually there is only one position for the tonos in each word. Different
position is different word or mistyping. So, you get one domain name with
the tonos, one without. If the domain name had a final sigma, one domain
with tonos+normal sigma, one without tonos+normal sigma, one with
tonos+final sigma, one without tonos+final sigma (total four). If you have a
two word domain or more, you have to multiply these combinations.

As mentioned before, they are the same.

I agree :-)

The administrator/user of the domain name, not the registry.
