The first coin is a 1935s and somethings just off with the mintmark. it looks too lumpy but i cant distinguish omm or rpm or value. The next is an au red 1918 with some sort of die crack. the 1954d the mintmark is funky and way to close to the date.
Camera is fine - use a photo editing program to make photo larger - to make jpeg a larger size. I recommend Photoshop.
I hate to say it but they look exactly the same... Is that a loupe you are using in the pics? Maybe try experimenting with holding the loupe to the camera lens (this has worked with my droid x as well as my nikon) if you are unable to crop the pics closer.
