Hi! It looks like they belonged to a U.S. Navy sailor who served prior to and during World War I.

The one with the rainbow ribbon is a World War I Victory medal, and specifies military service between April 6, 1917, and November 11, 1918. The one that says Mexico 1911-1917 is known as a Mexican Service Medal. This is the US Navy version of the medal, and indicates that the sailor participated in a variety of engagements between the US and Mexico. The one with the red ribbon is a Good Conduct medal -- basically, the sailor served his period of enlistment without getting in trouble. The two clasps on the ribbon identify a ship on which the sailor served -- USS Vestal (which was a repair ship)-- as well as a shore station which I can't quite read from the photo.

The next one is the Cuban Pacification Medal, and this one adds a bit to knowledge of the sailor's service, because it's earlier than all the others. This one was for service in 1906-1909, so a couple years earlier than the rest.

Hope this helps! Let me know if I can clarify anything!
