What to do with content block permalinks – SEO Yoast

Hi All, I have been searching for over 4 days to an answer to my question but still can not find a definitive answer anywhere on the net.

I have created my first wordpress site using a modern, updated theme and several plugins such as SEO Yoast, WP Boxer and a couple of other plugins.
I have a Static Homepage made up of: 3 main (sticky) slides, some WP Boxer content blocks, a few slide-in widgets and footer etc.

What I am trying to find out with regards to Permalinks & an SEO or Indexing point of view is the following:

When I created the sticky slides it also creates 3 permalinks (one for each slide) example: https://mysite.com/homepage-slideshow/slider-1/ (slider-2, slider-3 etc)

When I create a WP Boxer content block it also creates a permalink for example: https://mysite.com/box/3-blocks-left/ (3-blocks-centre, 3-blocks-right etc)

All the different bits that make up my homepage for example: The sliders, the content blocks etc have their own permalinks.

I would like to know…
1. Will search engines index these seperate permalinks that make up my homepage? Which quite honestly look useless on their own when ‘view content block item’ (sort of viewing it as a post) button is clicked (in WP Boxer plugin) or in the case of sliders ‘view post’ button is clicked.
2. Using SEO Yoast, should I choose noindex nofollow for these seperate permalinks as I have already SEO’d the homepage as a whole seperate page on its own?
3. Or should I 301 redirect these seperate permalinks (probably 15 in total that make up the homepage) using Yoast to just point to the main homepage giving the homepage as the cananonical URL?

Thanks in advance to anyone who can shed any light on this!
