In Jainism, “Manushya yoni” (human birth) is counted as:

• 14,00,000 (14 lakh) types of Manushya‑yoni within the total 84,00,000 (84 lakh) jiva‑yoni. ( jainknowledge.com)

This does not mean 14 lakh separate human species with names. It means:

• There are 14 lakh different kinds of human births / birth-places according to Jain cosmology
• Covering all varieties of human regions, families, bodies, karmic conditions, etc.
• All are garbhaja (womb‑born) humans; there is no spontaneous (sammurcchana) human birth. ( jainknowledge.com)

Both Digambar and Shwetambar traditions accept this number (14 lakh Manushya within 84 lakh yonis); scriptures give the count, but do not list all 14,00,000 one by one. ( jainknowledge.com)
