It depends on the girls figure. It depends on the waist size. For a waist that is narrower than 23 inches her hips should be 30 inches or less. For a 22-25 inch waist her hips should be 27-32 inches. For a 24-28 inch waist her hips should be 29-34 inches. For a waist that is 27-31 inches her hips should be 31-36 inches. For a waist that is wider than 30 inches her hips should be 35 inches or more. It is okay if your hips are a little big or small for your waist. Remember you are still going through puberty and so you hips can suddenly start to swell or shrink.
size 5 to 6

Probably a US size 6 (which is UK size 8 I think...)
That is not small at all. A 46 inch waist is not petit. Now the jeans vary on your figure. Consider the size hips you have.
Vera Ellen had a 17 inch waist and Clooney had a 24 inch waist according to other online sources.
It would be slightly dependent on how tall you are, but with your measurements I'm sure a 'size 0' would fit you quite snugly. If you're going for a baggier look then a 'size 1' would be better suited. I have a 24 inch waist and 33 inch hips, and a 'size 2' from Hollister are kind of baggy on me.
Well these are my exact measurements and I would say at least a 12 but your chest can cause differing.
Somewhat bland but mildly interesting on general principles nonetheless.
