y1 = [85 83 82 87; 81 79 84 86; 82 81 89 87; 89 85 87 80; 90 91 85 87];
figure(1), bar(y1,'stacked'); labels = arrayfun(@(value) [num2str(value,'%2.2f'),'%'],y1,'UniformOutput',false);
xticklabels({'NB','BLR','MLP','J48','CART'}); ylabel('\bfAccuracy in %','color','b');
ax = gca;darkGreen = [1,0,1]; ax.XColor = darkGreen; ax.XAxis.FontSize = 10; ax.YAxis.FontSize = 10; ax.FontWeight = 'bold'; hold off
legend({'2500 Dataset','5000 Dataset','7500 Dataset','10000 Dataset'}),legend boxoff
%% I need legend in 2X2 lines (i.e., 2 Rows & 2 Columns) AND values of y1 should be labled inside the corresponding box

Try the following:
y1 = [85 83 82 87; 81 79 84 86; 82 81 89 87; 89 85 87 80; 90 91 85 87];
figure(1),
b = bar(y1,'stacked');
labels = arrayfun(@(value) [num2str(value,'%2.2f'),'%'],y1,'UniformOutput',false);
xticklabels({'NB','BLR','MLP','J48','CART'});
ylabel('\bfAccuracy in %','color','b');
%
for k = 1:4
xtips1 = b(k).XEndPoints;
ytips1 = b(k).YEndPoints;
labels1 = string(b(k).YData);
text(xtips1,ytips1,labels1,'HorizontalAlignment','center',...
'VerticalAlignment','cap')
end
ax = gca;
darkGreen = [1,0,1];
ax.XColor = darkGreen;
ax.XAxis.FontSize = 10;
ax.YAxis.FontSize = 10;
ax.FontWeight = 'bold';
hold off
legend({'2500 Dataset','5000 Dataset','7500 Dataset','10000 Da,taset'},'NumColumns',2),legend boxoff

Dear Simon
Good work
But it is not working in 2016b version perhaps.
Any modification can conclude my work.

You can define the number of columns in the legend object using the property NumColumns. Use the following:
legend({'2500 Dataset','5000 Dataset','7500 Dataset','10000 Dataset'}, 'NumColumns', 2, 'Box', 'off')
