I'd probably just put them all in the same hash:

require "yaml"

filename     = "data.yaml"
characters   = ["Molly", "Trade"]
saves        = {location: "Southeaster", hunger: 10, life: 76}
settings     = {display: "1360*960", render: "high", saves: "manual"}
program_data = {characters: characters, saves: saves, settings: settings}

# File.write may not be in some older versions of Ruby
File.write filename, YAML.dump(program_data)

loaded_data = YAML.load(File.read filename)

require 'pp'
pp loaded_data
# >> {:characters=>["Molly", "Trade"],
# >>  :saves=>{:location=>"Southeaster", :hunger=>10, :life=>76},
# >>  :settings=>{:display=>"1360*960", :render=>"high", :saves=>"manual"}}
