No, you don’t need a dweller in a storeroom.
While the storerooms don’t produce anything, placing E-type dwellers in them will increase their happiness, improve your average happiness rating, and give you more caps on your daily ratings. It also counts toward the “Place # dwellers in the correct room” objective.
The Storeroom requires 12 dwellers in your vault before it can be unlocked.
You can be lucky enough to place dwellers in each room, increasing the chances of successfully boosting production. You don’t have to worry too much about a cockroach infestation or setting the room on fire when they’re in the room.
Lounge – unlocks at 40 dwellers – increases Charisma. Game Room – unlocks at 50 residents – increases luck.

To increase the chances of having a baby, make sure that either the male or female dweller has a high Charisma score (at least 7 or higher). Be wary of male residents who have high Charisma scores. They can easily get their partners pregnant and before you know it your shelter will be overrun with babies.
Room. SPECIAL. Weapons. SPECIAL in Fallout Shelter works a bit differently than in other games because there are no skills in this game. Each SPECIAL attribute increases the efficiency of dwellers in different rooms, during battle or when performing certain tasks.

In Fallout Shelter on Android, one of the possible goals is to fully merge four rooms. However, as stated in this question, you can only merge a maximum of three rooms.
