I hope this sort of post is allowed here. I’ve been working on this but I’m not very knowledgeable on guns so I’m not super sure of my guesses. Specifically I’m trying to work out what sort of ammunition each uses, but the type/model of gun would help too.

Thank you! Yes I agree that #1 is the grease gun. At first I thought it was Baretta M12 but with a longer barrel mod (maybe a butchered suppressor) but you’re right it matches the M3.
After some more searching I found the wikipedia page for the indonesian armed forces equipment: https://en.wikipedia.org/wiki/List_of_equipment_of_the_Indonesian_Army
I think 5 might be the Pindad SS2, based on the stock (mainly the foresight and the number of holes in the heat shield thing) and 6 might be the Pindad SS1 based on the stock shape, the cone-looking formation near the front sight, and lack of a rail.
I would assume that 4 is the Pindad P1, a clone of the browning hi-power just because it standard issue for the TNI, and i doubt anyone will get a better guess at it.
#2 stumps me because of the stock, it looks similar to the SS2, but the raised bit on the top of the stock with the 3 holes near the rear doesn’t fit, and the loadout with the rails and GL doesn’t match anything I saw.
Pindad seem to not be shy about cloning parts of other guns, so that might be why they all look so familiar, yet different.
Based on that info, I wouldn’t be surprised if #4 is the Pindad P1. Just seeing the front/top, I could easily confuse a 1911 and a Hi-Power… or even a Tokarev maybe. But, it looks like they do have 1911’s listed on that page too so it’s a toss up from me.
And I think you’re right on the Pindad - especially the SS2 for #5. Gas block/front sight, receiver, stock and caliber all match. I’d never heard of these - nice find!
I’m a tiny bit proud of guessing that it was piston operated based on the gas block : D
