"Yo ho ho" was made popular from a shanty in Robert Louis Stevenson's Treasure Island. It was already in use at the time and is likely a variation on "Yo Heave Ho".
"Land Ho" is an exclamation from a lookout on the sighting of land.
"Tally Ho" is an exclamation from a huntsman on sighting a fox. It was used as a signal for RAF pilots to attack during WWII.
