nearly all the species mentioned are NOT for beginners. A small and probably easy to care for species is Furcifer lateralis lateralis.
To make some points clearer:
I bet 100$ that nobody here has real Trioceros rudis. The animals called rudis are sternfeldi or cf. sternfeldi aka red rudis.
Sternfeldi have very often deathly mouth problems.
Trioceros jacksonii merumontanus need very cool nights, high humidity and spots
