Currently there's +----------+-------------+------------------------+-------------+ | | Audio Calls | Messaging | Video Calls | +----------+-------------+------------------------+-------------+ | Consumer | Duo | Messages (SMS/RCS), | Duo | | | | Hangouts | | +----------+-------------+------------------------+-------------+ | Business | Voice | Chat (Formerly | Meet | | | | Hangouts Chat), Voice | | +----------+-------------+------------------------+-------------+ Business products are available for consumers too, but with limitations. (For example, consumers can't make bots for Chat.) Hangouts is almost gone, starting a video call just makes a Meet and sends the link as a message, the messaging still works but has been folded into Chat (They interop for now at least.) so there's no reason to keep Hangouts on anymore really. Meet is for larger meetings, Duo is mostly for one-on-one calls but has group support now too. Chat is basically a Slack clone. Messages is Google's SMS/MMS/RCS app for Android and it requires an Android phone with an active phone plan but it has a web interface for composing messages on your computer. Voice does phone calls, voicemail, and SMS and MMS with a number from Google, and is separate from Messages. I don't think Voice can do RCS which is odd considering how their pushing it on Android.
