Hello Claude,
in order:
1- cap badge 8th Heavy Artillery Regiment (in italian "artiglieria pesante", WWII)
2- cap badge 11th Field Artillery Regiment (in italian "artiglieria da campagna", WWII)
3- cap badge Carabinieri (without V.E. -> post war?)
4- Marine badge, there is Savoy knot so I think it is from royal era, but I don't know what is it. Sorry!

Regards
