Here are the core Jain conduct names (Mahavratas), i.e., the five main vows:

1) Ahimsa — non-violence in thought, word, and action 2) Satya — truthfulness 3) Asteya — non-stealing 4) Brahmacharya — celibacy (celibate conduct for ascetics; for householders it is voluntary self-control) 5) Aparigraha — non-possessiveness or non-attachment

If by “1 aachar name” you meant something different (e.g., a specific aachar for laypeople or a particular Jain text), please tell me exactly what you’re looking for and I’ll provide the precise name and meaning.
