I want to make the Cockroff-Walton multiplier which will be powered by 12V 5A 21kHz power supply.
I want to order components,but as i seen on the internet,nobody posted Cockroft-Walton multiplier with such low input voltage.
Would it be enough to generate arc?

12 Volts is very low to start with.
You will need thousends of stages to have some arc.
You will create arcs when the voltage is in the kilovolt range.

I think with a 12 volts starting voltage the sum of the forward voltage of the diodes would limit the number of stages that could be used. I think you first need to step up the 12 volt 21Khz with a transformer. There may be a chance of finding a transformer in an OLD switch mode power supply. I say old because modern switch mode power supplies will use a higher frequency than 21 Khz.
