How many leos?

How many female leopard geckos can I house in a 4'x2'x18" enclosure?

It really depends on the leos themselves, even if they appear to get along you'll have to keep a close eye on them to avoid any aggression/fighting during feeding times and such. If you have enough hides, I'd assume the enclosure could house between three and five evenly sized females. Either that, or it'd be a paradise for one spoiled female.

I know a lot of people do successfully house females together, but it's something you shouldn't take lightly. They could be best friends for years in the same enclosure, then one day they decide they want their personal space, or they want their friend to share more food, and bam. Bites, Fights, possible missing toes and tails, or worse. If you plan on feeding them all separately, then that might lower the chances of a food-related fight, but I'd recommend supervised visits between the females you want to house together for a few weeks before putting them all in their new enclosure.

Since I'm fairly sure two of my three Leos are females, I may try housing them together at some point later on. They've met each other a few times outside their tanks, and they actually get along very well, but I'm not going to take any chances until I'm 100% sure they're females. I'll note, they've also been out around my male, Ace, and he tolerates them really well...He'll follow Nami around, and he even tolerates both Nami and Sora climbing on him and pawing at him.

I think a 4’2’18” is a little too big. You want about 10 gallons of space per gecko.

I have four AFT geckos together in a tank about that size, and I think I could fit in one-two more if I really wanted to. But as it is they have ample space for each of them to do their own thing in a different hide if they wanted to. Leos are about the same size, so you could probably do 4-5 leopards in that tank, considering that everyone's personality is fit for it.
