Problem: I would like to use Access to rename the default WordPress roles, and I would like to use Access to restrict individual custom fields based on user role.

Solution:
Access is not designed to rename the default WP roles. This will require custom code that doesn't relate to Toolset, which therefore falls outside the scope of our support forums. A quick search led me to this post, which shows you how to display different names for each role (but not modify the slug):

Custom field permissions are managed at the Field Group level, so it's not possible to manage individual fields. There is also Types Custom field conditional display, but it is currently limited to conditions based on custom fields and not User role. My advice is to split these fields up into separate groups, which you can restrict based on User role with Access.
