wm-thompson I assume you have answered your first question via CoPilot and now know about galleries.

Your second question - "Is there a way to drop a container into this section on the right side of the page such that all of the other displays are moved down?" No because you can't put a container inside a form. But you can have several forms on the same screen all linked to the same selected item in the gallery and just display in each one the fields you want.

So in the screenshot below there are 4 containers. The vertical gallery, which I've renamed to galPilots, is inside the far left container. The middle container contains the first form, but not all the columns, only a subset of them. The bottom right container also contains a form with our columns from the SharePoint list but again only has some of the fields..

For both of these forms the item property is  galPilots.Selected

So the 4th container in the top right has the 3 checkboxes which, in this example, just checks the checkbox based on the flight hours in the last 12 months, for example checkbox B has the Checked property set to 

Your 3rd question - "I would also like to know how I can make this app such that it is not the only page.  I would like to have perhaps a couple more page with similar content that the user can choose to view."

Having multiple screens is a normal part of any app. So add a new screen from the link on the left:

Then to navigate between screens add a button and in the OnSelect property enter for example Navigate(scrSupplementary, ScreenTransition.Fade)

On the new screen I've added a container and a form and set the item property of the form to the same galPilots.Selected as before and chosen the fields to display. For the label showing the pilot's name the Text property of the label references the variable so is "Supplementary Information for "&varPilot

Come back with any questions about this.
