Is it possible to build a membership section with toolset that has the below -
1. New member registration form accessed by a specific user role (we want specific staff only, to be able to add users)
2. The same staff users to be able to delete or edit these users, without having access to default admin user areas. (hidden link)
3. Customize the new user registration notification and reset password notifications.
4. Create a Network, e.g Live notifications, User groups, messaging etc.
#1 Yes, this is possible with Toolset Access and Toolset Forms:

#2 Deleting requires either access to the Admin area, or custom code applied to a CRED Edit User Form, that deletes the user upon submitting the form.
The CRED API to hook to is cred_save_data():
https://toolset.com/documentation/programmer-reference/cred-api/#cred_save_data
The WordPress function to hook in is delete_user():
https://codex.wordpress.org/Plugin_API/Action_Reference/delete_user
Editing users is again possible with the instructions found in #1
#3 You can add notifications to the CRED Form used, and customize it however you want:
https://toolset.com/documentation/user-guides/automated-email-notifications-with-cred/
But native default WordPress notifications are not part of this.
#4 No
The toolset is not a Social Networking or Communication tools like Buddy Press or WPSymposiumPRO
Thank you for information.
