It is said creatures have different number of kalas, but avataras have more kalas than others. The number goes until 16 for a complete avatar (like Sri Krishna). Also the quantity doesn't mean "better", because all avataras are same God taking differents bodies.
I found 2 diferent list for these 16 kalas, on here:
- Daya – Compassion
- Dharjya – Patience
- Kshama – Forgiveness
- Nyaya – Justice
- Nirapeksha – Impartiality
- Niraskata – Detachment
- Tapasya – Meditation and Spiritual Powers
- Aparchitta – Invincibility
- Danasheel – Beneficience, Bestower of all wealth in the world and nature.
- Saundarjyamaya – Beauty Incarnate
- Nrityajna – Best of Dancers
- Sangitajna – Best of Singers
- Neetibadi – Embodiment of Honesty
- Satyabadi – Truth Itself
- Sarvagnata – Perfect master of all arts, such as poetry, drama, painting etc.
- Sarvaniyanta – Controller of All
and this other
- Annamaya
- Pranamaya
- Manomaya
- Vigyanamaya
- Anandamaya
- Atishayini
- Viparinabhini
- Sankramini
- Prabhavi
- Kunthini
- Vikasini
- Maryadini
- Sanhaladini
- Ahladini
- Paripurna
- Swarupavasthita
Here in this answer it is very well explained different kinds of avataras
amśa, amśāmśa, āveśa, kalā, pūrṇa and paripūrṇatama (or paripūrṇa)
but now I'm asking about 16 kalas
