Those enclosures need a lot of work. Here are a few things that I would recommend changing.
1. Get rid of the substrate! Chams can accidentally ingest it and become impacted, which can be deadly. A bare bottom enclosure is best.
2. Add more foliage. They need a lot more space to climb and hide than they have now. horizontal climbing branches would be a great addition as well.
3. Remove the water dishes, they do little more than breed bacteria. Chameleons do not drink from standing water.
4. If you have a Chameleon in each of those enclosures, place something between them so they cannot see each other. If they can see each other they may become very stressed and in time very ill.
5. You will need to get larger enclosures soon. The minimum recommended cage size for a male Panther Chameleon is 24"x24"x48". Your little enclosures are fine for little babies, but will need to upgraded by the time they are about 6 months.
