re: How do I exclude one or two categories?
Use the exclude_category shortcode option.

re: Is there a limit for shortcodes used?
No, you can use the shortcode on as many pages as you want.

re: The problem with the category is solved. I see, that I do not have to exclude any but include the ones I want to have. It worked fine!
Yes, that is another way of doing it.

re: I need to change the appearance of Zipcode and Town. It has to be much bigger or maybe bold. You told me to use CSS. Is there anywhere an example page? How do I change just the two?
No I do not have any examples. You can use the browser CSS inspection tool to find the class and add your own CSS to do anything you want to the zip and city. Example:

#cn-list span.postal-code,
#cn-list span.locality {
  font-size: 24px;
}

I’ll send the invoice in a few days, thanks!
