For better understanding the roots of the expression let's look for example: For instance, I've got some money on me, right?, and I have to pay for something. You ask, how much money are you going to take (to pick up) from me -> сколько с меня (вы снимете денег)?
Another example. He's got some money on him and he has to pay. How much money, they are going to take from him -> сколько с него (снимут/сниму/снимет/снимем = возьмем денег)?
Сколько с нас (you pay for yourself and for your company)?
Сколько с неё (from her)?
Сколько с них? (they)
Сколько с вас (from your lot)?
