Very nice collection. I like to way the seller worked on the trees. Everything is in proper pots and soil for bonsai, and the branches are already pruned to create a basic structure that is good. They probably also took time to angle the roots so the tree has the best front and nebari. Very obvious when looking at th ficus trees.

Not sure, but I think Buxus is the boxwood. It is a small shrub that stays small and clusters quickly, which makes it easy to prune into topiary ball shapes. The ones on display were pruned very thin to show off the branches and trunk, giving it a traditional bonsai shape. It would be fun to develop the branch ends into thick pads of leaves (cloud pruning).

See I cannot help myself, I just ramble on. Thanks for sharing, and the kind mention. Almost missed this post in my feed.
