When passing is prohibited: Passing to the right is dangerous and a motor vehicle may overtake and pass to the right of another vehicle only under the following conditions:
(a) When the vehicle overtaken is making or about to make a left turn.
(b) Upon a highway within a business or residence district with unobstructed pavement of sufficient width for two or more lines of moving vehicles in the direction of travel.
(c) Upon any highway outside of a business or residence district with unobstructed pavement of sufficient width and clearly marked for two or more lines of moving traffic in the direction of travel.
(d) Upon a one-way street.
(e) Upon a highway divided into two roadways where traffic is restricted to one direction upon each of such roadways. (VC 21754)
Never. The only time you can pass another vehicle on the right is if there is a lane on that side you can go into to pass it.

In general, only when the lane to the right of the other vehicle is an actual traffic lane, and not always then.The traffic violation "passing on the right" is generally interpreted as using the shoulder to pass another vehicle.
Five vehicles or more.
you can pass another vehicle waiting to turn right on its left side by going off the road you can stop in it to off load passengers pedestrians, who are already crossing the road when the red man signal starts showing, have right of way
That depends on the country in which you live. Some countries drive on the left, others drive on the right and this will affect which side you pass another vehicle.
For a country with right side traffic you should as a rule overtake a vehicle on its left side. But on a bicycle it's allowed to overtake on the right side as well.
When two vehicles meet on a steep road where neither can pass, the vehicle facing downhill must yield the right-of-way by backing up until the vehicle going uphill can pass.
There are only two times when you may pass to the right of another vehicle: on a two-lane road when the vehicle you are passing is about to turn left and on a highway with at least two lanes of traffic moving in the same direction.
(in the US) On multi-lane roadways - The far right lane
