How To Spawn and Loop Multiple blueprint actors?

I have different blueprint class actors with a spawn point that spawns the object into the scene, but I am having trouble figuring out a way to randomly spawn more than just one object at a specific time and loop.

To be more clear, the effect I am trying yo achieve is to randomly spawn an object from list of objects in a scene, and when they are destroyed, respawn another object randomly from the list. Does anyone know a away I can go about this?
