The ones under the “?” are (top to bottom):

Chamfer

External threading

External threading

Also:

I’m very glad to see that you have them all oriented correctly.

I do consider “LH Turning Tool” and “Facing Tool” to be synonymous. Along these lines, it is very rare when I need to turn away from the headstock (LH turning). It is even more rare when I need to face radially outward.

Very nearly 100% of the time, I face from the outside in; if the cutting tool is not centered perfectly, this results in a nub. If the nub has perfectly straight sides, your tool is too low. If the nub has a rounded profile, your tool is set too high.

Yes. You have them marked correctly. It looks like the factory put the etching on the top of the tool.

yes sir, I learned that center tool thing in the beginning
 
I think the third one down from the top (9) in post #22 is actually an internal boring tool- doesn't look like the right shape for threading
The first one of the ? tools sure resembles an external threading tool. The 3 below that could be used for cutting pulley sheaves- I have made some like that when I needed to make a small pulley
