I found the datasheet for the first motor here [cnc25.free.fr]. It says they are rated at 3V 1.2A per phase. That makes them a reasonable match for the drivers used in most 3D printer electronics. The torque is a little on the low side, so you may have to accept lower acceleration than usual. Don't use them in direct extruder designs, use a geared design instead.
The second one is less ideal because it has a lower rated current and higher phase resistance (and presumably inductance), nevertheless it should still be OK, especially when used with 24V electronics. I didn't find any torque data for it.
