It is hard to make a blanket statment about that seller. The chanel quads appear to be obvious fakes (blue and brown with non-standard look both with the Nymphea name). The 8 brush MAC brush set with the roll has already been identified and stated as being fake in this folder. The full-size pigments are questionable, as most of the boxes do not have a label. Even with the label they might be fakes, as seen in this thread

The pigment jars aren't pictured as they need to be to identify many of the other obvious signs of being a fake. Pictures of the back and bottom of the jar would help tell for sure if the labels appear authentic at least. In light of other fakes, the pigment vials may or may not be fake. Some of the colors on the vials look really off, but you cannot rely on that alone.
Bottom line is that it appears that this seller is selling at least some fake items, and I wouldn't buy from anyone who does sell some fakes. Most of the remaining items (single shadows, empty palettes, brush cleaner) look like they are probably authentic based on the labels and packaging. They may have multiple product sources and may not realize that they have some fake items in their inventory.
