What titles apply to non-monastic/lay Buddhists? (upasaka/upasika savaka/sravaka)
you might get a few answers but here is my thought:

Śrāvaka (Sanskrit) or Sāvaka (Pali) means "hearer" or, more generally, or"disciple", or "one who sits near", "one who lend ears"

Gender neutral and describes all level of achievements.
