They would die pretty fast ig , if they got somebody like Orsted help then they can survive . Immune to magic isn't that good , a wolf can still kill you easily :D

If I understand correctly what you are asking, someone immune to magic would not get transported, as long as he activated the nullification at the exact timing and it is powerful enough. Similarly, someone with extremely large mana pull big enough to exceed the mana in the transport magic, could actively resist the transport and remain in the same place like it was explained in LN vol 14.

@Zozo916 thank you for the answer but also if someone was not transported like everyone else do you think the higher ups in the kingdom might of tried to blame them since that person was not teleported.

Yeah that is a probable consequence. Imagine someone just standing normally at the middle of a valley created by giant teleporting bomb. Of course strong people would notice and either try to kill him or hire him (or perhaps avoid him because he's too strong).
