The Lee Universal decapper will work for all 3 of those caliber including the 50AE. I know this because I happen to have some 50AE laying around and just decapped one to be sure you could use that die.
Of course you need the separate shell holder for each caliber.
Note, the 308 is the same as 45ACP for future reference but many think 9MM is compatible with 223 and 380 (called 9MM Kurz in Europe) But, the 223 and 380 are the same base and the 9MM is slightly larger and requires a different shell holder. Just adding some semi-unrelated info to this common misconception
