Before asking the community for help you need images that can be enlarged and clear. You should also indicate locality they are from and the age. These all look modern, but those trying to help you need better information. It would also be good to know what project these relate to and why you need determinations.
sorry if the images are not clear as i took it by my digital camera through the eye piece of the binocular microscope. I have no camera attached to microscope to get better images. These species belong to K/Pg successions of the Farafra Oasis, Western Desert of Egypt as studies for my PhD.
It depends on the quality of your digital camera, but usually playing a bit with the different options (macro vs. infinity, autofocus vs. manual focus, focus on center vs. focus on whole area) can make a huge difference when taking pictures from a stereo microscope...
