習慣 (しゅうかん) is the most general term for habit or custom, covering both personal and social. 慣行 (かんこう) refers to established practices, often in business or official contexts. 風習 (ふうしゅう) specifically means traditional customs or folkways, like festivals or rituals. For 'good custom', 良い習慣 is the safest choice unless the context is clearly professional (then 良い慣行) or traditional (then 美風 or 良き風習).
The direct translation 'グッドカスタム' is not used in Japanese. Always use a natural Japanese expression like 良い習慣 or 美風 depending on context.
