L = {'A','B','C','D','E'};
X = [ 1, 3,0.5,2.5, 2];
H = pie(X);
%
T = H(strcmpi(get(H,'Type'),'text'));
P = cell2mat(get(T,'Position'));
set(T,{'Position'},num2cell(P*0.6,2))
text(P(:,1),P(:,2),L(:))

I got the answer. I have to just put 'FontSize' at the end text comment.
text(P(:,1),P(:,2),L(:),'FontSize',18)

Hi, this was a really helpful answer. Thank you @Stephen Cobeldick. I am wondering if you can help me relocate some of the external text labels. You'll notice "NH4+" and "Na+" are written too close to the pie chart...
Thanks in advance!
