There is a risk.
If 12903 Golden Temple Mail reaches NZM with delay of 1-1.5 Hr then You can miss 12424 from NDLS because you have to travel from NZM to NDLS so alteast 1 Hr buffer time is to be needed.
Better to prefer 12059 Kota - Hazrat Nizamuddin Jan Shatabdi Express from KOTA to NZM & then take some EMU Local...
more... train to reach NDLS. so you could get sufficient time to catch 12424 from NDLS.
