Tre supermen a Tokyo (1968) as Fisherman

Attila (1954), as Hun Pic added

Matchless (1967) as Doctor

I pirati della Malesia (1964) in the roles of Prisoners in 2 separate prison camps, so presumably 2 separate roles.

There may also be a 3rd role as a house servant in the bottom left of the last image, but I'm not absolutely certain about that one.

Marco Polo (1962) in dual roles as a Monk and a Minister.

Come rubare un quintale di diamanti in Russia (1967) as Chinese announcer.

It's not clear who he's announcing to since no audience is shown.

Rascel marine (1958) as Japanese officer

The Quiet American (1958) as Hotel waiter

La figlia di Mata Hari (1954). Like most of the other Asian actors, he plays multiple roles:

As Palace servant (at least I think that's him - on the right)...
...as Japanese officer...
...as Javanese officer (or rebel) with fake grey beard...
...and again as Javanese officer (or rebel) in two scenes, but without the fake beard so clearly not the same role as above.
