the mount diameter suggests to me it's for the Argus (C3) not a mount I'm familiar with specific lenses in, so I can't get reliably closer.
I'd guess at 35mm f/3.5 as these are among the more common, and had multiple versions. |

I think I need to give more tips:
a. The lens shown here are the lens head only without the focusing helicoid.
b. They are not wide angle lenses.
c. They are made for 35mm film cameras.

Edit: front element diameter may clue what focal length since we know lens is for 35mm camera.

Not many lens made for 35mm film cameras has a removable lens head.
Last two tips:
a. The lens on the left has 3 elements while the lens on the right has 4 elements.
b. Both of them are first party lens from the same maker.

Do I understand correctly these are interchangeable fronts for a multi-focal length lens body containing focus helical? Or from a camera with focus parts inside?.

3 elements and 4 elements; perhaps the viewing and taking lenses for a 35mm TLR?
