I believe this does what you are trying to do:
% Create some fake data [Use your real data instead]
m = 5;
C = cell(3,4);
C = cellfun(@(x)[(1:m)' rand(1)*(1:m)'],C,'UniformOutput',false);
% Get the size of the cell array
[cellrows,cellcolumns] = size(C);
for i = 1:cellrows % Loop over the rows
figure(i); % New figure for each row
hold on % Make sure each plot does not overwrite the others in this row
for j = 1:cellcolumns
plot(C{i,j}(:,1),C{i,j}(:,2))
end
end
