I may be able to help you out with D. andersoniana and D. pulchella (Pink Flower). Unfortunately I have just found out that the guy I get alot of my seeds from has passed away over the weekend.
You could also try and purchase them from the Australian Carnivorous Plant Society. I have attached a link. I believe Khoas is the seedbank officer for the society and I don't think you need to be a member to order.

Let me know if you are interested in the others. Cheers.
