They are planes. They leave contrails just like jets at high altitude. Notice how they follow similar fight paths (apart from one that flies right to
left), and turn in more or less the same place. That's typical conventional aircraft behavior.
Edit to add:
Just for the record, meteors
can appear to travel upwards and away from the horizon, though they may actually be loosing altitude in respect to
the ground. This is because Earth's surface, and the atmosphere are not flat.
Consider this scenario: You are facing south, and a meteor appears directly above your head in the sky (the "zenith"), and proceeds to travel
downwards towards the southern horizon from your perspective.
Now imagine that someone else is a couple of hundred miles away, and looking north in your direction at the same time. From that person's
perspective, the same meteor will appear to travel upwards and
away from the northern horizon.
Understand why you can't discount meteors because they seem to be traveling upwards now?
