Deck 5 can be used for PA personnel, scientific personnel, or refugees and tends to be mission dependent. Otherwise, it can serve as spare storage or a backup place to sleep and meet up should Deck 2 be damaged. No one really seemed to have recommendations for what to put in Deck 5, so I went with expanding the ability of the Plumeria to carry troops or refugees depending on missile profile, especially since Deck 5 allowed for them to quickly get to the Vehicle Bay to deploy. It should be noted that the new Modular Pod is also intended to have various optional forms as needed for the crew loadout, possibly even having a modular pod be for the deployment of Power Armor or for refugees to quickly enter or exit the ship.
