How many fishes are there in the tank ? How often you change water and how much? Also how much you feed them ?

3 goldies in a 11gal(44liter) tank is overstocked as a single goldie may require 7-8 gals minimum so it would be Better to keep two goldies at that tank but still you may have problem later on as they tends to grow very fast and soon they would outgrow your tank so plan for a larger tank in future

what about the water change?

since your tank is overstocked you should perform 25% water change 2wice a week.

Is there any way that you could test the water parameters i mentioned ?

Ask the local fish shop about getting the water tested for those parameters as for a fully cycled tank ammonia and nitrite should be 0 and nitrate should be below 40

Btw what filter you have ?

And do you use any water conditioner in your tank water ?

Forty litres is a little more than ten gallons, and a ten gallon tank is about 50 mm (20 inches) wide. A 40 gallon tank is almost four times larger.

Or is it centimeters??

Where on earth did you hear that 3 Goldfish in an 11 gallon tank is Overstocked? They would have to be Extremely Large Fish for it to be overstocked. I have 8 Small Goldies about 1 and a half inches long (head to tip of tail) in a 30 Litre Tank. They have been there for quite some time (at least 6 months to 1 year at a guess). They are completely healthy ..... the only thing that affects them is that they Do Not Grow very much.
The general rule is 1 inch of fish to each inch of the tank length: So if you line up all fish along the front of the tank (excluding Tail), that will tell you how many are okay in the tank.

The one inch per gallon rule applies only to torpedo shaped fish, not those with large bodies. Goldfish have wide bodies, eat quite a bit and make a relatively large mess for their size. The large mess is mainly in the form of ammonia, and more goldfish make more ammonia. Bacteria associated with the nitrogen cycle convert the ammonia, in three stages, to harmless stuff. However, the beneficial bacteria have a limited capacity and when that limit is exceeded, the aquarium suddenly crashes.

An aquarium operated at or near the limit of its biological capacity has no room for errors like over feeding or skipping a partial water change. Goldfish are tough, but they are not likely to be healthy or happy swimming in toxic ammonia.

Guest Fish you really do have a lot to learn about goldfish requirements for tank size. Do some proper reading, and research as many folk on here have, then come back with a more informed statement.

If those are five gallon water jugs in the lower picture, it appears that your aquarium holds a little over ten gallons.
