I assume you mean n1=n(0:799,0), etc?
But why do you have to make each column in the 2D array into a separate variable? Isn't the data fine where it is?

This should work just as well with the original 2D array. Assume you have the lengths of the columns in an array lengths=[800,830,840,...], you could do something like:
for i=0,24 do begin
openw,2,'test'+strtrim(i,2)+'.dat'
printf,2,n[0:lengths[i]-1,i]
close,2
end
