seleucid empire (referring to the user here), I'm glad you are interested in history here, but don't get your feet too drenched in the sea of false glory and honor that the layman would impose upon history. If you're here hoping to crack the code, as it were, and determine precisely or anywhere near-precisely how many warriors were mustered by each faction in these wars, I'm sorry to say it's not going to happen. Also, you should ask yourself if you mean the numbers of warriors (those who would fight) or the combined numbers of warriors and those others who would be there to offer a variety of support measures (we don't need to get into this of course)?
