Luis Vallejo calls this Yama momji Japanese maple. Yama is mountain and momiji is Japanese maple (Acer palmatum). In English, you'll sometimes hear this variety referred to as Mountain maple, which is the original, naturally occurring Japanese maple. Because of the differences in the leaves, I'm guessing that this was originally several different trees that were planted very close together, rather than a clump planting
All the photos shown here are from Luis Vallejo's Jardin de Bonsai. With the exception of the tree above, they're all pieces of bonsai rather than the whole tree. You might call them art shots
Persimmons. We've featured several Persimmon bonsai lately. Now we've got one more in full fruit, though this time just the top half of the tree

This one could only be a Stewartis
Looks like a flowering quince with a small yellow bird?
We'll leave this as simply Pine
