Down route cover: usually none at a minor destination, perhaps one crew at a major one.
At bases: some carriers will have crew on airport standby, but it's more usual to be at home with a nominated time within which to report.
Captain cover for an F/O: only if the Capt is current to fly from the right seat, which is normally the case only for trainers.
