14-42 EZ? It can't really do Macro, so you'd need a diopter of some kind.
The 60mm is a fine macro lens; I don't know if it will fit your port....I only know Nauticam, not AOI, port/lens combos. Nauticam has charts of what fits shat; probably AOI does too.
The 45mm is a nice macro length, but is more of a portrait lens than a macro lens on its own. It would need a diopter of some kind too. The f/1.8 is not very useful for macro...you need more depth-of-field than that.
