You can start cuttings from these, but I would say to start with six inch cuttings and put them in 4, or 6 inch containers. A 5 gallon container, or any large amount of soil for that matter, will bring about way too many problems with how much to water, when, and keeping fungal infections away from wet soil that has no roots in it yet to absorb that moisture.
I am going to include a couple of articles that will help here:
