How much is 5G NSA NR TTi value, or it will use same TTi of LTE as in option 3x the signaling is on LTE end?

TTI understanding is same like in LTE

The early 3500 NR cells will be using the FR1 range (450 -6000MHz). Therefore, it should be supporting numerlogies of n =0, 1,2 even if operating in NSA implementation. This should translate to TTI values of 1ms, 0.5ms & 0.25 ms respectively.

5G NR has 1 ms subframe. TTI is 1ms as in LTE. But based on the chosen numerology i.e. sub-carrier spacing of 15/30/60/120/240 MHz can have 1/2/4/8/16 slots i.e. 14/28/56/112/224 symbols.

It is a Slot, and a Slot is variable.
