What about the lengths of the strings? Are 'ABBD' and 'EEECBAABBEEEDDD' both allowed (in different cells of course)? Or so they all have to be 5 characters long, like 'AAAAA' and 'AECCB'?

Try this:
clc;
numberOfCells = 10; % Whatever you want
letters = cell(numberOfCells, 1); % Initialize.
for k = 1 : numberOfCells
% Get random length between 1 and 9
thisLength = randi(9);
% Get all letters from A up to the max allowed.
% Numbers are randomly chosen so that repeats may occur.
m = 64+randi(thisLength, [1, thisLength]);
letters{k} = sprintf('%c', m);
end
% Show the cell array in the command window.
celldisp(letters);
In the command window you'll see:
letters{1} =
DBBAGED
letters{2} =
ABC
letters{3} =
AA
letters{4} =
A
letters{5} =
DBCA
letters{6} =
ADDB
letters{7} =
CDFECCD
letters{8} =
BCCB
letters{9} =
AABB
letters{10} =
FFCBEE
