The top semi auto pistol is a Spanish Ruby 7.65/32 ACP and are fairly common but don't hold the value like Mausers, FN's, Beretta or Lugers. The revolver is a top break Iver Johnson which were very common in nickel finish in the early 1900's. The Iver Johnson is probably a small caliber rimfire or a centerfire like 32 short Colt, or 38 S&W which should not be confused with 38 S&W Special (aka 38 Special Ctg).
I can not see the IJ well enough to determine which caliber it is chambered.
The Iver Johnson revolvers have very little appeal with low value but are neat family heirlooms. I would not fire either handgun without first being inspected by a knowledgeable gun smith or collector.
Maybe someone else more knowledgable will chime in.
Here is a link to a Ruby which was for sale that will give you some more info.
