Yes, the ItemBuilder Web Part can provide entity instances to multiple consumers at the same time.
There is one limitation: The ItemBuilder Web Part can provide entity instances to consumers only from a single external system instance (LobSystemInstance) per Web request. Therefore, if you attempt to retrieve related entity instances from a different external system instance than the one that the source entity instance lives in, it does not work. A workaround for that case is to provide an entity instance from the ItemBuilder to Item Web Part, and then provide the entity instance from the Item Web Part to the Related List Web Part.
