1.) Would you charge for directing help, directing questions, common errors, and directing classes?
Hell no.
2.) Do you think that people should charge people for these things?
I feel like, as long as they’re not coding your whole story, they really shouldn’t. But, oh well, people will try to get money out of anything 
3.) What is your opinion on this matter?
Personally, I think it’s wrong and makes you seem desperate to make some money quickly. Also, it feels like you’re scamming people by charging for something that they can get for free from a lot of other places.
Take care, and don’t get tricked into wasting your money
