In the full Narada Purana (Purva Bhaga) this is chapter 56, verse 193.
In order, Aditi's star and the two-god star are the big stars. The others are equal. Their lengths in ghatikas (24-minute unit) are thirty, ninety and sixty.
Simple meaning: Short stars last 30 ghatikas, big ones 90 and the rest 60.
क्रमादभ्युदिते चंद्रे नयत्यर्घसमानि च ।
The Moon moves through these stars in turn. A list of clan-group stars begins.
पितृद्विदैववस्वाख्यास्ताराः स्युः कुलसंज्ञिकाः ।
These stars form the clan group. A second list, of non-clan stars, begins.
अजाह्यंत्यकभौजंगताराश्चैवाकुलाह्वयाः ।
More stars form the non-clan group. The rest are mixed.
