Emco 240 Tool Turret
But the sensors for turret position is done before

This is the information I found inside the motor cover
And the 2 speed wiring diagram.

I use a mesa 5i25/7i76, don't know if it has enough inputs?
Yes, the 7i76 has 32 input. That should be plenty for even a very complex lathe. And you can add up to 48 more on the serial expansion port on the 7i76. And then up to 384 more on the spare header on the 5i25.

That looks like it might work, though the description says "Gray code" and I thought that your truth table looked like straight binary.
However, that is a detail. Using the built-in "carousel" HAL component might be easier through software upgrades, but it needs a bit more HAL effort to make it work. (only very slightly).

OK, that's useful, and presumably the relays to make all that happen still exist in the control box? Do you have the required 3-phase supply?

I really have no clue how to wire it since my electronics knowledge is almost 0. I really appreciate the help though! But I think I can't provide you the information you need.
I just want to get the turret working. And installing a stepper motor is a bit more straight forward I think

But not sure how to approach the following. And what's the most user friendly method.
I can set the turret as a rotary axis. 360 degrees is a complete turn.
8 tool positions. 45 degrees for each tool.
The turret needs to move behind the locking pin. And a few steps back to lock it in place.
So maybe it needs to go +/- 48 degrees forward, and 5 degrees back to lock it.
Should work fine and I can manually add the G0 for the turret turn to my code. But that's not very user friendly. I would need to edit the code each time.
Isn't there a easier solution to accomplish this?

You could run the stepper motor in velocity mode, that way it doesn't matter if it slips.
