The charges on trophies do stack, just like the rooms and crafters. You get the extra of the most recent friend to charge and the others simply stay there till the next time you can collect them. Because of that, multiple charges on trophies are only really useful to people who TT since anyone who doesn't can only collect them twice a day at most. Personally, I love it when friends charge my trophies since it lets me collect a few thousand energy points every time I TT.
