How to create loops with plugin

Hi,

I was trying to find a plugin for my problem, but I coulnd’t. I’m not an expert of php code this is why I tried using a plugin.

My problem is.
I have 3 pages (page1, page2, page3) and 3 categories (cat1, cat2, cat3). Each of the page should have a loop by category like this:

page 1 should should only posts from cat 1.
page 2 should should only posts from cat 2.
page 3 should should only posts from cat 3.

On top of it I would like to keep the original Home page (I’m not sure if it’s affecting the solutions or not).

I have tried using ‘Category pages’ plugin, but it shows only post titles, but i would like to see more details about the post (the whole post all content before ‘More…’ tag in the post).

Additionally I’m using theme called ‘Graphene’.

I’m not sure if I have described my problem properly. Please help me with this issue.

Thank you for your help!
