Hi there! This question is fine here, but as it predates written history, you may also want to crosspost it to r/AskAnthropology.

Although this is probably a better question for r/AskAnthropology, I can answer it here. At the moment the only concrete evidence to suggest any interactions between species is the DNA shared between Homo sapiens, Neanderthals and Denisovans. So there were sexual interactions between Homo species, but whether they lived or worked together is unknown. Several other earlier Homo species lived at the same time period and regions as each other, but there is no evidence to suggest any interactions between them.

Edit: spelling
