Multiplayer Variable System

Hello Everyone, I am making a game where you build star ships to fight one another. It will be multiplayer, so, say, one player with 20 fighters and 8 frigates could face another player with 12 fighters, and the 20 fighter 8 frigate would win. I need to store variables for health, damage, shield, etc., of each players' fleet, and then pit those variables against each other. My question is:

A) How would I format these variables to be individually stored for each player B) How would I format a system where the variables from each player could be accessed and compared C) Any networking tips that would be helpful, if anyone has done something like this before

I know this is a lot, so if anyone could answer one or more, I would be grateful. I am using photon and c#. Thank you all.
