Every coin that uses KGW should apply the fix as well asap right?

Yes, I think so.

Any idea if digishield or dgw (version2) are susceptible to the same exploit?

Have not yet dig too deeply on it, but:
Digishield: not the same, but possibly similar. KGW counts a lot of blocks to calculate adjustment, digishield only one, so it quite different. In KGW, attacker can 'jump over' the block in the future, which is not possible with only 1 block. Not yet sure, but there might be another TW exploit: Can you generate 2 blocks with dT less than 2xtarget so difficulty won't rise? If you generate block with dT 0, you get diff +25%, if I calculated correctly. next question: can you generate a block with -25% difficulty with less than 2*timespan? I think you get only -12.5% with 2 blocks time, so this hole is not open :-). But not sure if there are others.
Edit: this is dogecoin digishiel, don't know others..

DGW: possibly, quick peek reveals no fix, but it might be there, have to make deeper look at it to be sure.

DGW is not exploitable. It is not effected by this exploit, this has been confirmed. Darkcoin > *.
