Your CPs:
•Venus flytrap, giant Z11
•Nepenthes ampullaria var. Cantley's Red, x2
•Nepenthes ampullaria var. Harlequin, x2
•Drosera capensis, var. all-red, x3
•Nepenthes bicalcatrata, x2
•Heliamphora minor, x2
Fall into three cultivation groups.....
1) Require winter dormancy with bright light and a seasonal change in photoperiod and cold temperatures in dormancy: Dionaea, and to a lesser extent Drosera capensis
2) Require tropical, hot conditions with nights always above 16C and days in the 20s and a constant 10-14 hour photoperiod of medium to low light: Nepenthes bicalcarata & N. ampullaria (x2)
3) Require warm days, daytime temperatures around 20-25C and nighttime temperatures around 8-12C, and a constant 10-14 hour photoperiod of very bright light: Heliamphora
D. capensis will probably tolerate what you throw at it, with the exception of low light.
Sorry to be negative, but these plants just WILL NOT grow happily together. Eventually some WILL die.
