Need header changes and categories for every page

Hi! A few minutes ago I update my catch everest theme to pro version and have some questions. First of all I want to tell that I made also child theme and it work. I delete "search" from header. Now I want to move Header text on space between header image and space where "search" was, so it will look in one line: image - little bit free space - header text - a little bit free space. I can do it only with text under image or delete image or text, can move it. Second my question about blog categories. I made 3 pages and I need for every page different category, so if you click on 1st page you see posts only from 1st category, the same for 2 and 3 page. I can do only "front page" for all posts and "post page" (only for one page, cant do the same for 2-3 pages). So I need to make the same also for 2 others pages. My site only on my local host, but if you need some images or information, I can do it also can make some photoshop to show how I want see my pages if I'm not clearly describe my qestions. Thank you!
