the number in teh first Picture is a footage number in ink of the Base side of the film. the number would be semi unique for every foot of film. the numbers were used when editing the film so the work print could be matched to the Negative. the "H' is a code for the type of film, but I no longer can find my old list. the 25 is the ink machine number. and the Little ink lines every 4 perfs on the other edge is a way to indicate that you have "safety Film" and not Nitrate. if you look at the base of the film with an oblique light you may be able to see the ink. the advantage of the ink method was the person loading the movie camera could confirm the typeof film,and sometimes would put the footage number on the Camea report to help the editor. That method did not work with REM-Jet and so they went to just latent Image Numbers for colour film, and eventually B&W.
as far as the other picture that is the normal Movie edge print at the time. the 15 is the strip number that was cut out of the master roll. off the top of my head I think 35mm got up to strip 38. Plus - circle-triangle means the film was made in 1994. If you look closely at the word "Safety" you should see a small dot between the letters. if it says "S'AFETY" it would be from Rochester., SA'FETY would be Toronto.
