Single file star like sky objects moving across sky in straight line from NE to SW

Pulled in to driveway and both of my children said Dad those stars are moving.  Star sized lights in sky, not as bright as north star, typical brightness of ISS moving overhead.  Single file, one after the other, they appeared from the Northeast and moved across the in a South West direction.  After the first half of the objects almost all the same distance apart, two of the objects moved across the sky in the same why but this time very close to one another, almost in tandem.  These two appeared more orange in color than the others. One or two others appeared moving slower and traveling in a different direction.  They continued moving across the sky, crossing by orians belt.  After 17-23 moved across the sky over 5-7 minutes they stopped.
