The 5 armer is a Triumphe similar to Victory but for the "waist" near the arm ends. 116 BCD, down to 35 teeth Miche make them or did until very recently.
The 3 armer is a Sport 3320, 116 BCD down to 36 teeth which was a standard size so TA and many other rings fit, but a little ingenuity may be needed to fit double rings. Much loved by the USA "art bike" types.
Every day is a school day.
I just looked at the chainrings.
