Idenfy help needed

[mvahtra]

Hello !

I am a noob in this forum,so please take some excuses if I am in wrong place. Recently I bought a military lot from German aucktion site. There were various pieces in different era from WW1 to nowdays. I have a problem to idenfy these items that are in pictures. The golden "V" pin has dates 1869-1959, the blue "50 V " pin has marked as "333" gold. The aucktioneer can not idenfy these items also,the google picture search did not helped me. In my mind "V" sounds like "victory/veterans"?
Thank in advantage for any clue I can continue..

I can tell you that none of these pieces has any connection to the 1957er awards and that most (I think all) are not German.

The red-and gold collar patches with the "VU" or "UV" monogram are Italian.

The star with the laurel wreath bottom right is an Israeli police cap badge.

The hexagonal pin bottom left is a religious item ("XP" ["Chi Rho"] being a Christogram).

A badge identical to the one at bottom center is currently on sale here where it is identified as a cap badge from Cameroon:

(Or almost identical? The color of the bottom field of the shield is yellow on the specimen for sale, but looks white on your last photo, although it does look yellowish on the first.)

No idea about the two stickpins.

Not recognising any of these items...certainly no 57 connection I can see?
The Green/Orange/White shield could be national colours linked to a flag??
Any makers marks you can see???
