Problem with category

hello, I am using the zenon them and I sorted my product by category. You can see the display on this page https://site.kathlinargiro.com/the-designer-collection/. I have 3 questions:
1- how to get rif of the number into bracket next to my category name? (it is in yellow on the page)
2- how can I make the display of my category bigger and more playful?
3- When you clic on the category only 6 products show per page and I would like 8 product (or all my product) per page. How can I solve that?

Ps: I am not good at coding.

Thank you for your help
