carla --- It's apparent they do speak of guardian angels . They believe there are angels following each publisher around out in field service .
They believe that demons appear to some people in a human look just so they can confuse them into believing the immortality of the soul doctrine that most of the christian world teaches . The only humans they believe are resurrected at this time are the 144k since 1919 or whatever date that was christ chose the WTBTS as his wife . They go directly to heaven to rule with christ so cannot be found playing tricks on humans . According to the WTBTS . I don't believe anybody has been resurrected yet .
