Any help would be appreciated

 

[MINENAZ16]

6 : could be a Dutch shrapnel
7-8 : russian rifle grenade type "Djakonov"

No2 looks like a 20mm oerlikon with a hispano proj for a M21 case

No 2 is 20mm Oerlikon made by Michigan Die Casting Co, Detroit,MI. Mk3 is a steel case and looks like a plated Drill/Dummy. Projectile looks like a Hispano as tomsk said.
If a factory Drill it would be firmly crimped into the case.

#6 is a Dutch shrapnel. It is the Granaatkartets van 10 cm (caliber 105 mm) with the Time & percussion fuze nr. 3.

 

[Alpini]

For the ID of No.5 a picture of the fuze thread is required but most probably it's a German 9 cm Gr.14.

No.3 is a German shell for the naval 5 cm Kanone C/95. But the fuze looks weird - better pictures required.
