Change the default post category archives design

I hope you’re doing well. I am currently working on a stagging site to change my theme to GeneratePress. I found solution for many issues regarding the default design of the theme. But now I am stuck on the post category archives page. I wanted to show 2 post on my category archives page, the theme default is single post with big pictures. Also I want to rearrange the layout, starting with the post image first then title and other information.
Please help me out with this. I am a free user so I don’t know if changes are possible. I am not good with code, so a clear guide form you would be much appreciated.

I am working on localhost for my stagging website sorry I couldn’t provide any link for reference

Thank you.
