How long should I brush my Angora rabbit for each day?

I'd use a small comb rather then a brush. Brushes do nothing for long hair. Just like a longhair cat would need to be combed daily to remove any tangles or mats, you should do the same for the rabbit.

As long as needed. There really isn't a set amount of time. Most of the time you just need to worry about mats. During shedding season they need extra grooming to get out all that loose fur.

Get a comb. They work far better with long hair.

It won’t be the same amount of time every day. It’ll depend one hat he’s been doing and how tangled his hair is. You want to comb out any mats and brush him til he’s shiny.

Rabbits groom themselves, the goal when grooming an Angora is to make sure there are no mats/tangles, so as long as they are mat free you are doing fine.

5 minutes.

You should COMB it not brush it. Brushes aren't really good at separating the hairs in pets like this so the coat can end up matting. http://www.thecapecoop.com/how-to-groom-angora-rab...
