Generally this should work. Use graythresh and im2bw to make a mask of white dots and then use bwconncomp to count them.

Check this example, here . pay attentention to the line that it counts the grains

cc = bwconncomp(bw, 4)
cc.NumObjects

MATLAB: I am not getting the BoundingBox

See my Image Segmentation Tutorial where I demonstrate that: http://www.mathworks.com/matlabcentral/fileexchange/25157-image-segmentation-tutorial---blobsdemo--

MATLAB: How can i separate all the connected regions in a binary image and display them individually.

Use bwlabel() and ismember

[labeledImage, numRegions] = bwlabel(binaryImage);
props = regionprops(labeledImage, 'Area')
% Compute all the areas.
allAreas = [props.Area]
% Display each blob in its own figure.
for k = 1 : numRegions
    thisRegion = ismember(labeledImage, k);
    figure;
    imshow(thisRegion);
    drawnow;
end
