No, these are called "Introduction points", entry guards are something else.

If it loses connection to an introducton point it will immediately
choose a new random node to use and once the circuit to the new
introduction point is established it will announce it.

If you lose them or if someone managed to steal them (because then the
thief with your key can impersonate your service)

Yes, absolutely. only a dew minutes and you are online again at your
new location with the same .onion address

No. Nobody knows the IP address of your service because you only
connect via 3 tor hops to the Introducton points (and to the
rendezvouz points), none of them ever learns where the service is
located.
