How to square handwriting variation?

[Bluetoes101]

The problem is the ones in between, to the right of the flower on the image I posted, I would maybe call that j, but I wouldn't be confident its not a slightly more upright d. However other people would say its definitely not X/Y, and it's hard to say how you decide who is right unless you have examples like yours in one basket and all the "unsure" in another.

These are from the posted example with that d / j, is it built like the s or r?
It's just hard to say who's right on a bunch of them imo
