str=s(randi(numel(s)))

Do you want capital or lower case letters? You can just use the ascii representations
char(97:106)
or
char(65:74)
If you have the Statistics Toolbox you can randomly sample from those "populations"
idx = randsample(65:74,5); %choose five letters at random
char(idx)

I suggest asking as a new question and linking to this post, but I wouldn't be surprised if this question has been asked already somewhere.

it is the function that can generate random alphabet between the given alphabet.. one more thing you can also input the ascii code of alphabet
function ra=randa(a,b)
%a=any number or alphabet
%b=any number or alphabet
l=double(a);
k=double(b);
if a>=65&b<=90
ra=char(randi([l k],1,1));
elseif a>=95&b<=122
ra=char(randi([l k],1,1));
else
error('you are entering wrong number or alphabet');
end
end

Your ranges are off
char(60:90) %what you use
('A':'Z')+0 %actual
Your use of > and < is confusing. Use >= and <=
