How to Add Multiple Admob ads in single activity?

Question

In this activity, I want to add multiple ads. but I am unable to do so. I want that in this activity, there should be an ad below the image, and one ad should be in the middle of the post's content. The ad below the image should be banner, and the one in the middle of the content should be native. For example, I have also attached a screenshot.
