FWIW, most of that is in the documentation for the Groups and Scenes app. (I think the "Use group device to indiciate..." options are newer, but they are simple and just do what they say: creating a group using the Group and Scenes app makes a group device, and you can choose if you want that device to be on of one or more member devices are on or--and this is mutually exclusive, so the other option will disappear when you choose either--off if one or more member devices are off.)
Rule Machine does not have options like these, but the whole Rule Machine app is somewhat "advanced" to begin with. 
They've demoed some things in RM on at least one Hubitat Live episode before and have a few videos up on their YouTube channel that may interest you. Otherwise, the Rule 4.0 docs are good place to start there, too.
