As long as the box is not touching the 5, you can label it and call bwlabel to get blobs 1-6 and 8. Blob #7 will be the box.
% Make sure it's binary
mask = yourImage > 128;
[labeledImage, numRegions] = bwlabel(mask);
% Extract blobs 1-6 and 8
maskWithoutBox = ismember(labeledImage, [1,2,3,4,5,6,8]);
If the box touches the 5, then you're going to have to do tricker things (morphology like imopen or imerode) to separate them.
