In the full Narada Purana (Purva Bhaga) this is chapter 56, verse 177.
The fixed ones are Rohini and those named Uttara. The quick ones are the Sun's star, Ashvini and Pushya. The common ones are the star of the two gods and Agni's star.
Simple meaning: Rohini and the Uttaras are fixed. Hasta, Ashvini and Pushya are quick. Vishakha and Krittika are common.
वस्वदित्यंबुपुष्याणि विष्णुभं चरसंज्ञितम् ।
Dhanishta, Punarvasu, Shatabhisha, Pushya and Shravana are moving. Four are soft. The Purvas and Magha are fierce.
मूलार्द्राहींद्रभं तीक्ष्णं स्वनामसदृशं फलम् ।
Mula, Ardra, Ashlesha and Jyeshtha are sharp. Each star group acts like its name. The ear-piercing list begins.
समृगेज्येषु बालानां कर्णवेधक्रिया हिता ।
Ear piercing for children is good in these stars. The next list is for elephant work.
