The older small stamps with Washington and Franklin and the postage due stamp are almost certainly the common varieties. It is almost impossible to determine one of the rare varieties from a simple camera pic. You'd need a very high resolution picture, be able to measure the perforation, and in some cases identify the watermark (cannot be done from front view picture). That means you need to invest in some philatelic equipment/supplies.
The other stamps are either very common or common -- realistically retail for 1c to 10c.
You have a good start to a beginner's US collection. Don't know how you acquired this, but hopefully you will find interest in the stamps themselves rather than their financial value, and consider taking up stamp collecting. It's a great hobby!
