These look like typical inexpensive tumbled material found in tourist shops and for kids. These often include dyed agates, quartz, tigers eye, obsidian, jasper, etc. 3 looks like a tiger's eye, 4 snowflake obsidian, 5 is a dyed agate, 7 quartz. Others are too hard to tell from the photo. If you want specific guidance please post one a time with good photos.
