That depends on the implementation of your security policy. It decides
if a principal has a permission for a given context or not.

The zope.app.securitypolicy.interfaces.IRolePermissionManager adapter
seems to do what you want. The spelling is essentially the same except
for that redudant third parameter. Use IPrincipalPermissionManager if
you want to grant/deny permissions to a principal (or group).

No. Groups are principals which means you can grant or deny permissions
to all principals within that group by working on the group.

Not that I know of, but I figure you could easily make one that is. Of
course, you could always use the zope.Anybody group to represent all
principals. I think groups are the more sensible thing to use here.
