There were many more than four in total. Right now they have more then four (there are completely separate messaging apps hidden inside Docs and Maps). It is easy to confuse them all, considering those apps got renamed often. By my count, there were four different apps called Hangouts (!), some existing at the same time: (1) The original Google Hangouts, which replaced Google Talk. (2) Google+ Hangouts, which was video only. Google+ also had a text messaging app called Huddle. (3) Google Hangouts Meet, a video chat aimed mostly at the workplace. By the time it was launched Google+ was dead and buried. The “hangouts” was later dropped, making it just “Google Meet”. (4) Google Hangouts Chat, the equivalent text chat device. They also dropped the word “hangout” from the name, but it was launched as “Hangouts”.
