I've seen most of those before... let's see:
#1 is the "large tinclad" Ouachita. The turretlike structures near bow and stern are basically rifle pillboxes (not sure they used the term "pillboxes" at that time, though).
#2 is a ram-- I think the General Price, captured from Confederate service at the Battle of Memphis. Yes, I'm pretty sure #3 is another view of the same boat (with the "timberclad" Conestoga visible to the rear).
#4 looks like an Ellet ram to me... Monarch or Queen of the West, perhaps. I'll need to look that one up. (Maybe Switzerland?)
#5 and #6 are the same boat, the tinclad St. Clair.
#7 is the Ouachita again-- note the 'pillboxes'. I'm not sure I've ever seen that particular image before.
#8 looks wacky to me. Will need further study.
#9 (Tinclad 53) is the Naiad.
#10 is a "double ender". A very similar (but not identical) photo is identified as USS Conemaugh.
#11 (Tinclad 8) is the Signal. After she was lost, her number was given to the Grosbeak, but that one was a sidewheeler.
#12 is the timberclad Conestoga (this and similar photos are widely misidentified as Lexington).
#13 is the General Price again.
#14 might be Monarch. I've seen that photo somewhere before... need to check.
#15 is the Naiad again.
