I'm Miles from the Social Care team at Shopify. Thanks so much for reaching out with your question. Are you using a free Shopify theme? If so, I've listed some possible options for you. If you are using a third-party theme, or a theme purchased from the Shopify Theme Store, you'll need to reach out directly to the developer for assistance in customizing the theme.
The screenshot you provided doesn't show me where you'd like this change, so I'll work through the homepage and product pages. If it is somewhere else that you would like to make the change, could you please reply to this thread with a direct link to the page in question?
Collection Lists on the Homepage
To change the number of collections that appear in each row, follow these steps.
Featured Collection on the Homepage
To change the number of items on your product pages, you'll need to edit the product template coding. If you're using a Shopify theme, we can help you make the changes. You'll need to contact our Live Support Teams to have this actioned. If you're not, you can contact your theme developer to guide you on making the changes.

@Miles thank you for the answer
i mean this
I do not have the ability to control the quantity of products per line
There are currently 5 images in a row
I want there to be 4 pictures in each row
And so the images will be larger and more prominent
