Yes, what you purchased was the Core Plugin Suite which consists of all of those plugins. Each of the plugins has a set of features that can be modularly added to Core Engine based on the needs of your game. The Core Plugin Suite is expanded every time we make a major update so you can get access to new features.
If you have purchased CGC on any of our platforms (Itch.io, Patreon, Steam), you have the license to use all of those plugins for both non-commercial and commercial projects. You may even modify the plugins to best suit your needs and create plugins extending their functionality.
Party UI Type B and Type C are at the proposal stage and have not yet been developed. Party UI Type C will most likely be added to the Core Plugin Suite around the time of CGC v1.8.0 when the Enemy Cards & Decks feature will be implemented.
Let us know if you have any further questions.
