Video Hangouts in Google+ where participants must be at least 18 years old: When you start a video Hangout, you can restrict minors from joining it by selecting "Require guests to be 18+ to join this video call."
Video Hangouts without an age restriction: When you first join a video Hangout, you're agreeing to be in a Hangout with everyone who is there. Anyone in a video Hangout in Google+ can add others, including people who are not in your circles.
Remember, you can block or ignore someone at any time. When you block someone in Hangouts, the person will also be blocked in other Google products including Google+ and Google Chat in Gmail.
