While the photos are not definitive, I can tell you what some generally are/look like, and what a few specifically are, from the top of the first pic.
#1 - Looks like an early 1870-ish Prussian needlegun - an early boltgun.
#2,3,4 - Pre-1892 Mauser style, or Steyr boltguns, requiring ammo in ejecting clips for magazine feed.
#5, 6, 7 - I cannot tell from the pic
#8 - A sporterized Mauser 98
#9 - A sporterized Krag, either US or Norwegian (IIRC)
#10 - Unknown to me - a sporterized version of #12 below
#11 - Looks like a Mossberg rimfire
#12 - The military version of #10 above
#13 - Looks like it might be an 1894 or 1896 Swede, sporterized
#14 - Unknown to me
#15 - The Mosin
#16 - Whatever commercial sporter
Usually, pics from the other side of the rifles help some, too.
