One female and two males, aged 14 to 16, were each charged with wounding with intent to cause grievous bodily harm and burglary after Donner was found dead in Flaxmere earlier this year.
A fourth male teenager facing the same charges is expected to enter pleas next month.
Donner was found dead the carpark of the Flax Bar and Eatery in Swansea Rd, next to the Flaxmere Village Shopping Centre on March 4.
The four teenagers before the Hastings Youth Court were arrested and charged with wounding with intent to cause grievous bodily harm to the 40-year-old on March 16.
