Closed-face helmet mod, merge, replace, or rename??

[d3v]

SO once again I'm re-starting STEP and just reached the closed-face helmet mod which requires you to download 4 patches, but STEP guide does not say weather to merge, replace or rename when installing each of the 4 patches one after the other??

 

• "Improved Closefaced Helmets --FULL SET-- V0_9"
• "Improved Dawnguard helmets"
• "Improved Closefaced Helmets -- Dragonborn Addon -- 0_9"
• "improved imperial full face helmet - no cloth around the neck-"

anyone know?
