Theoretically? An infinite number of nodes publishers can publish to the same topic.

Practically? Until you run out of CPU, memory or network bandwidth. But even then there is no real limit, things will just get really, really, really slow and unreliable.

Any number of nodes can publish, as long as the message has the right type.
