What will come in place of the question mark in the following series based on the above arrangement?
$PRJ, \# L3, 7I2, @ON, ?$

To answer these questions, study the following arrangement of digits, letters and symbols carefully.

$6, N,P ,=,@, 7,1 ,\& , R, T, 3, L, ,B, \star, E ,4,\# , 8, G,H ,\$, 5, K,M ,?, 2, D,C$

Four of the following five are alike in a certain way based on the positions of the elements in the arrangement and hence form a group. Which one does not belong to the group?
