Hi! Friend of mine gave those devices to me. Can somebody please say what are those motors made for, and how they can be used. By now I do not have ideas how to use them.
Hi, They all appear to be small Stepper Motors.
For some general information, see THIS PAGE

The thing to do is measure the windings and figure out how each motor is connected - the 4 wire ones will
probably be bipolar. Finding the rated current will take some research...
