Scenario : Y-Wing V Firespray. I hit a Firespray with my ion cannon and give it one ion token. No effect on the firespray until it gets a second one because of its size as stated in the Firespray info sheet.

But does it still cop the one damage for the one ion cannon hit? Or does it only cop one damage when the second ion cannon hit is applied?

I played it last night as every ion cannon hit causes one damage and applies the one ion cannon token to the medium ship. The ion cannon effect of moving forward 1 doesn't happen until two ion cannon tokens are on the medium ship.

You played it correctly, but the Firespray is a large ship.

Didn't see this has been asked already in a better way than I did.

And what if large ship takes 3 ion tokens? Do he discard all 3 at the start of movement, or only 2 and the 1 stays on him?

We'll let FFG cross that bridge if they decide to make ships larger than the "Large" ships they have made (YT-1300, Firespray-31, and Lambda-class Shuttle).

All Ion tokens are removed during the Activation Phase.

Exactly……as per the rule insert that comes with the Millennium Falcon, Slave 1, and will come with the Lambda-class Shuttle.
