My 2 cents.
I. If you want "action photos" I would recommend the smallest focal length. (the 35mm)
This is because a manual lens is harder to maintain in focus, and the shorter focal length will give you a bit more room.
II. If you want "portrait", and they can pose for you, try the widest aperture (the f1.4) But depends on the max shutter speed.
III. For some "documentary style", (the kids sitting watching some other kids, and you taking the photos a bit far away) use the longest focal length, (135mm) at the widest aperture.
IV. Always keep the Sunny 16 rule in your mind. https://en.wikipedia.org/wiki/Sunny_16_rule
Or print a cheat sheet
V. If you want to freeze the action, try an ISO 400 film and adjust the exposure accordingly.
VI. To use the widest apertures, you can try some ND filters. (In the table I posted, the zones in gray need an ND filter)
VII. Try to keep a record of the shutter speeds you use.
This is because vintage cameras might struggle to keep an accurate shutter speed, especially on the faster side. This way you can test its functionality
For a 24-exposure film, I would try 3 groups of aperture-exposures to keep this record simpler.
