Hi Amila, You can combine four ESB artifacts in to a single ESB project. In the Carbon Application project, you have the capability to select what are the sequences, proxy services you want to include in to the CAR even though they all are defined under the same ESB Project. In other words, you can select either the whole ESB project or individual ESB components defined under ESB project.
