noob questions

[Ryugo0 0]

Hello, I am a noob in 3D and Animation
I saw some tutorial on youtube and I try to understand the possibility of mine imator mine and I have some questions

1 -> can we enable the "bending" option on cubes or it's only for the parts of mobs ?

for my first animation I want to use a llama, they are not included so I did one with retextured parts of mob, which brings two questions:
2 -> mobs blocks and 1.10 / 1.11 will be added in the future ? i saw the Dev is very busy these month.
3 -> how to make a custom rotation point on the parts of mob ? it's impossible ?

4 -> how to make a texture for a cube that has been stretched so that the texture does not appear stretched?
5 -> is there a way to import a 3D JSON file from a minecraft resource pack ?(with a mod ?)
6 -> I can export my animation as a PNG sequence, but can i directly export to GIF?

Thank you in advance for your answers and sorry for my english
