Tuna can spoil quickly at room temperature, typically within 2 hours. If the temperature is above 90°F (32°C), this time reduces to just 1 hour. To ensure safety and prevent foodborne illness, it's best to keep tuna refrigerated or frozen until ready to use.
How long it will take for raw meat to spoil will depend upon the conditions in which it is stored and it's use by date. If the meat is left out at room temperature on a warm day, it will likely spoil in several hours but on a cool day, it could take 24 hours to spoil. Stored in a refrigerator, raw meat would take 3 to 4 days to spoil if it is still within its use by date.
Not long
Milk typically spoils within 7-10 days if stored in the refrigerator at the proper temperature.
Breast milk can safely transition from fridge temperature to room temperature in about 30 minutes.

The time it takes for 2 gallons of water to reach room temperature will depend on the initial temperature of the water, the room temperature, and the surrounding conditions. In a typical room environment, it may take a few hours for 2 gallons of water to reach room temperature if starting from a colder temperature.
I would estimate a two hour limit for keeping yogurt at room temperature. Personally, I take it out of the refrigerator and eat it immediately. I see no need to keep it at room temperature.
Defrosting breast milk at room temperature is safe for consumption after about 2 hours.
That really depends on the temperature of the room it's in.
