Any info on their respective velocity, penetration depth and target medium density?

Any info on each of these rounds ?

Second from left could be .30-06, the next looks a lot like .303 British, not sure about the rest.

Probably so called ballistic putty, as it gives better(but not as "natural") expansion than 10% gelatine at 4°C.

As for cartridges:

It is NOT a .303 british, so while rather uncommon, this seems to fit the shoulder junction and neck shapes best.
.30-06 M2 AP as evidenced by the manganese-molybdenum penetrator core encased in a thick copper jacket and a lead filled tip.
Also 7.52 X 54R loaded with a steel core in the light ball variant
A Korean or Albanian produced 7.62X39 cartridge jacketed steel core with lead tip
7.62 X 35 (300 Blackout) using an all copper exotic bullet, likely a 110 grain Lehigh Defense HV Controlled Chaos Bullet
5.56 Nato M855 cartridge, which as the designation indicates is a copper jacketed steel base bullet
9mm Luger using a solid copper bullet, likely a 125 grain Fort Scott Munitions TUI bullet.

On a side note, it is quite interesting to see the BERDEN PRIMERS cut that way!
