None - that tank is far too small. On average, most goldfish require ten gallons as juveniles. When adults, they can require anything from twenty gallons to a pond. You simply cannot provide a healthy environment at any point in its life to care for a goldfish in that tank.
Consider upgrading.
In the meantime, also consider tropical fish. That tank, if you get a heater, is an ideal size for a betta and a couple ghost shrimp or cories. Stay away from tropicals that need larger groups to feel comfortable (like most tetras) and the more colorful fish with larger fins (like fancy guppies) as there just isn't enough room.

That tank is too small for a goldfish. You need to put a betta in that tank. But, you can't keep a betta with any other fish because bettas are very aggressive. You can't even put bettas with other bettas. Two bettas will fight to the death. You need a tank about twice that size for one goldfish.

Zero. Goldfish need at least 10 gallons per fish. Sorry try a beta.

That tank is barely suitable for one fish, maybe a baby that is being housed as temp measure. I would maybe look at getting some white cloud mountain minnows.
and please please ignore the persons advice above me that is the info that was given out in the 60's and is all urban myths and not true. It is cruel and inhumane to use feeders and live fish to cycle a tank. The modern mehtod is to fishless cycle with an artificial ammonia source

The easiest way to start a new fishtank is to buy several small feeder goldfish. They're cheap, so if they die you won't be out much money. Also, since goldfish are in the carp family, they grow to fit the amount of food and the size of tank that you have. A good rule of thumb is 1 fish for every gallon of water, so since you have a 6 gallon (25 liter) tank I would start with 6 goldfish. Good luck!

25 liters is only around 6.5 gallons, the smallest goldfish will need 20 gallons once fully grown and still needs nothing smaller then 10 gallons when it is a baby. So you can't have any goldfish for that tank.

Goldfish are filthy and disgusting. If you get one, you'll be cleaning that tank as often as you feed the fish just to keep the smell down. That tank is way too small, too. Get a betta.
