As mentioned the section, elevation, detail and worksheet markers can be copied and pasted from one file to another.
They will retain all their settings but not any 2D content (annotation) that may have been in them.
You will then have to re-create all the views for them in each file.
Layouts and masters can be dragged from one file to the other via the Organiser.
On the left side you open the file you want to copy from (you can browse or if you have all the files open already then you can choose one from the list - top left button in the Organiser).
So open the file that has the layouts you want on the left (and choose the layout view in the organiser) on the right side show the layout view as well - this will be your current file.
Drag what you want from the left to the right.
Now be careful because any drawings on those layouts or masters will be externally linked to the views in the original file.
So you need to select each drawing and choose 'Link to...' and choose a link to the internal view you want.
Or simply delete all the drawings so you have blank layouts and then place new drawings from your view map.
