Could someone help me with pages please?

I have set up a blog at https://www.sizeemup.com.
i would like to have the home page set up so i can post entries about anything in general i see fit. i would like my visitors to be able to click the photos/videos page from the top menu and see video or photo entries that wont necessarily be seen in the home page, same thing with the interviews page.

I am new to wordpress and web design and general and would really appreciate any help. I posted this post already but it seems i can’t find it today. Could someone help? Thank you.
