Loosen the spokes pulling to one side 1/2 turn, then go around the wheel tightening them on the other side 1/2 turn. Repeat till the wheel lines up better, or until you run out of threads on the tight side.
Then on to getting the rest with washers. Looks like you don't have enough axle to do it all with washers, so get what you can with dish first.
To dish the wheel a lot, it would require a re spoke, with one side a longer spoke, and the other side a shorter spoke.
