OBS natively streams to one live destination and one recording, though you can give it a URL in the recording path and stream to that too. Effectively sacrificing the recording to get two live destinations.
If you want more than two, OBS doesn't do that natively, but there are plugins that can. I don't know them off-hand, but you can search this forum as well as I can. :-)
Or, you can use an external re-streamer. (google search term) OBS streams once to that, and then it copies the stream to as many as you want to set up. Some re-streamers run on your local machine, others in the cloud, some paid, some free, etc.
