Backfired Pranks

The naughty four friends once decided to play some practical pranks on four different innocent guys. They learnt 4 different magic spells from the book "Learn Magic in 2 Days". Unfortunately, their magic backfired and instead of the intended victims, the girls themselves suffered from 4 different problems.
With the help of these clues, can you figure out which girl chose which guy as her victim, which spell she threw on him, and what problem did she face as a result of spell backfire.

Girls: Dis, Dip, Raj, Rich
Boys: Sur, Rot, Dud, Ank
Spell: Vomiting, Fever, Appetite Loss, Balding
Backfired result: Fainting, Freckles, Obesity, Pimples

1. The high fever spell gave pimples to the thrower.
2. The spell intended to make Rot lose appetite, made the thrower obese.
3. It looked like Rich has spent many long hours in the sun after her spell on Dud backfired.
4. The worst sufferer was Sur's torturer, as she remained unconscious for hours after her spell backfired.
5. The vomiting spell was not intended for Dud.
6. Dip was forced to order a new wardrobe for herself, as her existing clothes became useless after her spell backfired.
