It looks like Social is the platform that released v1, and the other ones are still in various stages of development.

My understanding is that “Bonfire Social” is very similar to Mastodon, with their own way of implementing certain features, and the other features in their funding campaign are still in development

Bonfire itself is a framework that implemented ActivityPub, on it you can build applications that make use of it without developing from the ground up. Bonfire Social is a social network similar to Mastodon. Collaboration is is about project management etc and allows one to host their own, but integrate with others, e.g. to synchronize milestones via federation. What they have in common is that both build on Bonfire and as such use the same protocol for federation. But they’re tools for very different jobs.
