If you have the Image Processing Toolbox, you could start by trying regionprops. This allows you to measure various parameters of each object; you probably then need to analyse the results for some known objects to work out which combination of parameters distinguishes the different object classes best.

can you help me to detect stars from this image

You could use a 2d-peak finder on a binarized version of the image. Search File exchange for some examples and see https://www.mathworks.com/matlabcentral/fileexchange/127449-mobile-phone-astrometry-explorer. Yolu could also use regionprops on a binarized image to find the bright regions - it will return the centers and radii. You might try a median filt first.
