The general rule is that two of a kind in the same Inventory tab cannot be stacked. You can't stack two Cash Shop coupons, Winter drop and Easter drop, Familiar and Winter drop, and so on and so forth.
I believe you can't use Family buff and Winter drop. The last time I tried Family + Easter Egg 2x drop, I got a message saying "One or more events are already in progress." So I had to cancel the Family buff.
As for the second question, all those drop rates will stack.
