%Example
A = num2cell([0;rand(10,1);0;0;rand(5,1);0;0;0;1]);
B = num2cell(char(randi([30 50], numel(A), 1)));
C = [B A]
%Find zeros in the 2nd column of the cell array
idx = cellfun(@(x) ~x, C(:,2));
%Remove them
C(idx, 2) = {[]}

"how if i want to remove all the row that has zero value in column 2?"
@RACHEL LYN JAHIRIN, In that case try this -
%Example
A = num2cell([0;rand(10,1);0;0;rand(5,1);0;0;0;1]);
B = num2cell(char(randi([30 50], numel(A), 1)));
C = [B A]
%Find zeros in the 2nd column of the cell array
idx = cellfun(@(x) ~x, C(:,2));
%Remove them
C(idx, :) = []
