This is an example of a gallery where you have multiple images coming from a single post, yes?
The available options for the ready-made gallery layouts can be found in the Gallery block (grid, masonry, collage).
There isn't the option to show only some of the images in the gallery, and include all the rest in the lightbox.
Views let's you generate HTML markup with dynamic content, so it would be possible to create such a gallery, but it is something you'll need to design yourself. You'll need to decide on a lightbox solution. You could enqueue the lightbox files which Toolset Blocks uses, which are located at vendor/toolset/public/blocks/vendor/lightbox/. For implementation details see hidden link.
Whichever solution you use, try creating a mockup with static markup (using something like Codepen), and once you have it working how you need, identify the repeating and dynamic parts of the HTML, which you can generate with shortcodes.
In particular, note how you can use the wpv-for-each shortcode to loop over repeating custom fields (i.e. your image field which accepts multiple values).
