Variants of Japanese coins [opgelost]

Hello,
I need help identifying these coins' variants. Their diameter is 24-25mm, their reverse is blank and I think they are all 1 mon new type (N#121454).

1.

2.

3.

4.

5.

Thank you

The second and the third look like the jumantsubo-sen and the fifth one looks like the akita-sen type.

The second one looks like the kameido-sen daiji type and the first one like the osaka nanba-sen katsuen type.

2, 3, 4 are 不旧手 FUKYŪDE types. (There are more than 30 varieties of these so beyond my ability)

1 has too much dirt to be identify. 😅

5 is 仙台石ノ巻銭異書短通 SENDAI ISHINOMAKI-SEN ISHO TANTSŪ

Hello,

Thank you for your help
