Hello,
Q1) Set Access to only allow view of content for post author
Yes, it is possible with shortcode [wpv-conditional], for example, in a single post content:
You can get current logged-in user's ID with shortcode:
[wpv-current-user info='id']
Get current post author's ID with shortcode:
[wpv-post-author format='meta' meta='ID']
Us above shortcode as condition of shortcode [wpv-conditional], like this:
[wpv-conditional if=" ('[wpv-current-user info='id']' eq '[wpv-post-author format='meta' meta='ID']') "]
//the content you want to hide goes here
[/wpv-conditional]
Q2) Post author can (via the front end) select specific other users and grant them access to the content as well.
There isn't such a built-in feature within Toolset, as a workaround, you can try these:
1) Create custom post type "member"
Each member post's author is different user, each user has only one member post
2) Setup many-to-many relationship between Post and "member"

3) In single post content, display a relationship form for author to connect current post with other "member" posts:

4) In single post content, display a post view:
- query "member" posts
- filter by
a) Post type relationship between between Post and "member"

b) post's author is current logged-in user:
https://toolset.com/documentation/user-guides/filtering-views-query-by-author/
- in section "Loop Editor", within shortcodes [wpv-items-found] ... [/wpv-items-found], display current post information, for example:
...
[wpv-items-found]
[wpv-post-link item="$current_page"]
[/wpv-items-found]
...

$current_page is used to retrieve data from the current page being rendered. It can be used inside a View loop to obtain data from the page on which the View is being rendered.

Meta HTML wrapped in [wpv-items-found][/wpv-items-found] will be output if there are any posts | taxonomies | users returned by the View.
