Math!
To calculate your equity of a range here's a basic example and you can build your equation around this:
Say you have KK. Villains range is AA and QQ.
Flop is A 6 4.
He has 3 combos of AA and 6 combos of QQ.
AA is 98% you are 2%
QQ is 10% you are 90%
Total combos of villains range is 9. 3 Out of 9 times you have 2% equity. 6 out of 9 times you have 90% equity.
1/3(.02)+2/3(.90)=.0067+.6 = ~61%.
EV calc bonus!
100 in pot, villain bets 100, EV of call?
EV of final pot - cost = Total EV
300(.61) - 100 = +83.
For YOLOs.
If villains range is AA, AK, 63, QQ and you have KK. You are still +2 EV. That's why I never fold.
Either get really good at doing this in your head, or just go HAM on a range calculator and do some equity calcs at home so you get a general feel for EV when you are at a table without having to crunch the numbers. I like

Edit: It also seems as if your asking if you should account for card-removal effects when multiple villain ranges are similiar. Like if you have KK, one player has AA, QQ, JJ the other player has AA, AK, QQ. For that, the calculations are going to be a lot more intricate since you will have to do a calculation for each hand in each range and then divide it by the probability of each of those events occuring and add up the total probability. For my example you will end up with 6 equations to put together to divide by probability of each event occuring. My advice is: don't do that. I don't think it's going to change your equity calcs enough when multiple villains ranges are more than 2 hands each.
