Is this normal swelling after 0.5 of Juvéderm? (Photos)

Yes, swelling can be typical. Icing and cold compresses may give improvement. I would wait a full 2 weeks before judging the results. If it is after the two week wait, you can have the filler reversed with hyaluronidase.
I hope this helps!

Swelling is common after lip injections and can persist up to two weeks.  You can use ice intermittently on the area and keep your head elevated on a couple of pillows at night for the next few days.  If after two weeks you still have concerns, return to your injector for an evaluation.

It's too soon to tell what your final results will be. You have swelling, which can be asymmetrical, and last 1-2 weeks after lip injections. If you're unhappy with your final results, you can have it reversed with hyaluronidase and try a different technique next time. See an expert. Best, Dr. Emer
