Questions about PlayStation versions of the games

So I’m gonna buy the og 1, 2, 3, and CV on the PlayStation store, and I have the rest of the series physically.

For 1, it says it’s the directors cut version. Is this the first one, or the DualShock version? (hopefully with the original music).

For 2 and 3, are these also the DualShock versions?

For 4, I’m just gonna have the og 4 for collection reasons and play the HD mod on pc. But for 5, is there anything different from any other edition?
