I am not sure how many Hunter 5 Squadrons were active in RAFG by 1957 but once they started to convert to Hunter 6 the numbers came down to 5.Three were based at Gutersloh - 14, 20 and 26 Squadrons and 4 and 93 squadrons at Jever. Conversion to Hunter 6 was completed by May 1958. Their principle role was air defence with ground attack as a secondary role. However more emphasis was being placed on the ground attack role by mid 1960 although very little practical training was provided to the pilots other than air to ground firing. At the end of 1960 another major change occurred with a major shuffling of the pack - some squadrons changing name plates while others ceased operation altogether. The Hunter 6's were replaced by FR10's and the Swift FR 5's retired.
I was there for some of that time and it is now over 60 years ago and my memory is not quite as good as it was back then.
