Well, these are the ones she wants. They've all been released, but I don't know how the size is going to affect things. None of the figures don't seem that big, but since the latter two items are multiple small figures packaged as a set, I don't know how much that'll affect things.
I doubt that stuff will require EMS. Unless those things are particularly heavy, you're probably looking at around 2000 yen maybe for SAL Registered shipping if those things are all about the size I'm guessing they are (like 6" or less and not in bulky blister packaging). If it's bigger and requires EMS, it will probably be on the low end of EMS pricing, 3k or so I'd guess.
Edit: For some more specific examples, I had a scale figure and a prize figure shipped together for 1.7k yen (SAL registered). When I ordered two fairly large figures together (boxes combined were over 2 cubic feet) that was too much for SAL so it was EMS only, 6.1k yen (no, that's not a typo).
