3 questions about Divi

I’ve been working at my website for over a week and I still can’t figure out how to customize the Divi theme to do three simple things.

1: Show my logo at the top of the page.

2: Show videos and images that I post in my blog on the front page.

3: Only show the top few lines of text posts on my front page.

Some of the themes that come with Divi do some of those and some of them do others, but I can’t figure out how to make any of them do all of them. I see things like these on other people’s websites all the time. Is there a way to make Divi do them? Or is there a different theme that can do them? Thanks.
