Add posts to pages

Hello I am brand new to wordpress and finding it quite complicated to use. I am using a theme called Architekt from dessign.net, but I cant seem to figure out how to link specific posts to specific pages, ie, it is a magazine type website and I want news posts to show up on the news pages and education posts on education page etc, I have tried looking it up on google but not figured out how to do it.

I have also downloaded a plugin for a twitter feed and would like it at the side but I can only see footer options under my widgets menu, so any ideas about that would also be handy.

My webpage is https://www.integrateni.com

As I said I am new (only started last night) and dont understand much, any help would be really appreciated. Thank you
