Have more than 6 articles in a category at first page

Using the AT posts column, I have 6 articles in each category, with image and some text (title and some words). I want to be able to add 3 or 6 more articles below these, but only the title, no image. I have searched everywhere, but I haven’t found an option with which to be able to modify the number of articles that I can have at the first page at each category. Only the number of articles at the slider. Can I modify something somewhere or is there any option I couldn’t find?

Thank you
