How can I remove the subplot colorbar label overlaps?

The easiest option is to use the 'FontSize' (link) name-value pair argument. (I cannot determine in what version that option first became available.)

@Star Strider, Thank you Star Strider. I only need 3 labels like the first two subplots

My pleasure.

Try something like this:

[X,Y,Z] = peaks;

figure
contourf(X,Y,Z)
c = colorbar;                                               % Return ‘colorbar’ Handle
tx = get(c, 'Ticks');                                       % Get Tick Label Values
txn = linspace(min(tx), max(tx), 3);                        % Calculate 3 New Tick Values
set(c, 'Ticks', txn)                                        % Set New Tick Labels
