<?php

$strings = ['n/a', '2 years', '3 years', '4 years', '5 years', '1 year'];

// remove first value from array and save it in a variable
$first_val = array_shift($strings);

//sort array based on string comparison
usort($strings, "strcmp");

//add removed value again at first position of the array
array_unshift($strings,$first_val);

//print array to see everything fine or not?
print_r($strings);

Output:-https://3v4l.org/4TcBi

Note:- In case n/a is not the first value then do like below:

This should work:

$strings =  ['n/a', '1 year', '2 years', '3 years', '4 years', '5 years'];
$numbers = array();
$albhabets = array();
foreach($strings as $v)
{

  if(is_numeric($v[0]))
    {
      array_push($numbers,$v);
    }else
    {
      array_push($albhabets,$v);
    }  
}
sort($numbers);
sort($albhabets);

print_r(array_merge($albhabets,$numbers));
