Hello,
I am trying to identify these American markings present on HC M1 smoke boxes and pots.
Thank you.

I believe the first one would be Edgewood Arsenal Experimental.

The 4th one would be U.S. Chemical Corps.

The 6th one looks like Huntsville Arsenal

Thank you for your reply.
Best regards from France.

Huntsville is a city in Alabama, I've never heard of it but I expect it was pre-1941, when an un-named Chemical Arsenal was combined with Redstone Arsenal right next to the city of Huntsville. Redstone is still going strong.
