Luggage Requirements for Bullet Train from Yichang to Wuhan

We are docking from a cruise and want to get to Wuhan via bullet train from the Yichang East station. However, we are trying to understand the luggage requirements on our site. We will have 3 suitcases and some carry on baggage. Will we be able to take all of this on? If so, how do we arrange this so we are not scrambling? Also, what are the different levels of ticket (Standard, first class etc.)? Would that enable more luggage? Is there any assistance for luggage?

Thank You!
