Theres really nothing challenging in it: Its a nested family, set to be work plane based. Then in the parent family, there are reference lines, and those are the work planes for the nested family instances. Constrain the reference lines, and yadda yadda.
For what you have pictured in the first post, the origin of the "arm" could be at one end. So host them on 4 reference lines, with an instance parameter for each length.
