Sure look like Box, Lorette. Please tell me, is the potting mix as heavy as it looks in the photo?
Box doesn't seem to mind a mix that is a little on the heavy side, but a few of the other trees on the plant list would certainly grow better in a lighter mix, something to remember later

By the way, price seems to be right.
As Taff said the two Ficus would well be worth getting onto. I have used Racemosa in the past (Darwin) and it responds rather well to Bonsai training. Virens is recognised as a deciduous tree, although not all ways with all trees. I have grown batches of Virens and have had trees which both dropped and held their leaves, from the same seed. They may also drop their leaves this year and hold them next. By the way, both of them would like some of that lighter potting mix.
I also note Woody has Podocaprus in their list, good tree to use if you have time on your hands. They are a slow growing tree - right up there with Black Pines.
I think there were a few more there as well, but my emory is old tonight and I didn't take notes, sorry.
