Good to know you have some satisfied simulation results!

A1: this would be anisotropic, so as long as you have proper refractive indices, you can simulate it. If it is diagonal, simply use them.

if it is a full tensor, you can transform it  https://optics.ansys.com/hc/en-us/articles/360034394694-Creating-anisotropic-optical-materials-in-FDTD-and-MODE

A2:  You can, but you will need either manually calculate the change of refractive index and import them, or you use CHARGE to simulate at different voltage:

np Density and Temperature Index Perturbation - Simulation object

Charge distribution to change in refractive index theory

np density - using 2D CHARGE simulation for 3D FDTD

Material polarization effects in CHARGE simulation

A3: no, unfortunately. Please contact mateial provider, or search online to get some information.
