Here is a clear Jain view on “next 14 Tirthankars”:

• In our current time-cycle (Avasarpini), all 24 Tirthankars have already appeared; Bhagwan Mahavira was the last (24th). So there are no “next” Tirthankars left in this cycle. In the next ascending cycle (Utsarpini), there will again be 24 Tirthankars, but their specific names are not given in the canonical scriptures of either Shwetambar or Digambar traditions.

If you intended “the last 14 of the current 24,” here they are (from 24th down to 11th):

1. Mahavira
2. Parshvanath
3. Neminath
4. Naminath
5. Munisuvrat
6. Mallinath
7. Aranath
8. Kunthunath
9. Shantinath
10. Dharmanath
11. Anantnath
12. Vimalnath
13. Vasupujya
14. Shreyansnath
