Sounds perfect to me!
I really loved visiting the Capitoline Museums. It's in the same area as the Forum.
Another favorite place is the Pantheon. I'm not sure about the lines or best times to visit the Pantheon as I was there years ago, but it's a pretty amazing place and once inside, should not take up that much time from your day. There's a cool elephant statue carrying an obelisk located right behind the Pantheon in Piazza della Minerva.
That is good advice!One thing I will warn you about since there will be 5 of you, each listening in on your individual phone. Sometimes it is hard to coordinate and have everybody on the same section, as it is easy to pause and also rewind. Sometimes it is best not to worry about it and realize some will be a little ahead and others a little behind.
