Hi Danny,
As Oliver said, it's not advised to plant them all together. You can plant the Sarracenia together in a pot certainly and they will grow outside if you wish. VFTs have never grown well for me outside, only when in a greenhouse. The Sarracenia don't need to be in a propagator, they will likely be more prone to rot. You won't need t4 lights on any of the plants if they are in a sunny south facing window. Purchasing a CP care book would be a great investment.
