Druids can have multiple summons up.

I didn´t know that until I actually miscasted a minor elemental when my greater one was up, here is my druid with his summons.

everyone can. you just can't have multiple of the SAME summon per character so you could do 4 conjure elementals one per char/6 ghouls from dance macabre/Create undeadx4/Planar Ally x w/e (lvl 6 cleric spell and never saw any scrolls of it so that's the hardest to get compared to the others)/Summon Cambion(which likely doesn't stack with planar ally on that char since that's also a planar ally choice) from infernal rapier/Animate dead x4/Find Familiarx4//conjure minor elementalx4/nature ally(the dryad one idr the exact name)x4/have thsoe 4 drytads all summon Woads. and all of those minions last till long rest :D

now could you actually GET all of those at the same time? maybe? many are available as scrolls druids would get both elemental conjures and the dryads by default so you'd just need create/animate dead scrolls for everyone and drop the planar ally

Yeah, I got an elemental spell early on, used it and took my sweet time to rest again. I didn´t want to lose him, he was practically carrying my party.

Would have made some fights much easier had I know this though.
