>>I have my 2 lizards in a 15-gallon tank. Plenty of space for both of them. I have a brand new Exoterra 15W Repti Glo 8.0 UVB tube and a 65 watt basking lamp. I feed them a combination of crickets (dusted with ReptoCal calcium and Vitamin D3 by Tetrafauna), shredded lettuce and sometimes baby bloodworms. They sit on some sort of calci-sand that is made for lizards just in case they happen to eat some of it is made of calcium and won't hurt them. Their setup is powered with aid of a timer, which is set to light for 8 hours, and turns off for the rest of the day. In the day their temperature is about 85-90 MAX and at night it is about 65 - 70. Since the one has slipped into a sleep, I have been feeding liquid calcium and plenty of water through a dropper. While doing this the lizard seems to fight me a little bit which tells me he/she is responsive. Other than that though I see an occasional open and shut of the mouth and slight head movement. Let me know if this helps.
First off I'm going to be blunt here so just take this advice as things you need to change and not as insults. You need to change almost every aspect of your husbandry or your beardies WILL DIE.
At one year old each of your dragons should be an average of 18-22 inches. A 15 gallon tank is completely inadequate for even one beardie that is one year old. A good sign you have been doing things wrong is that right there. I'm guessing your beardies are way smaller than they should be.
Their diet needs a lot of work. Lettuce is completely useless as it has no nutritional value whatsoever. I don't know about the bloodworms. Your beardies should have a salad available everyday consisting of nutritions greens and veggies. Some greens are collard, mustard, dandelion, turnip, escerole. There are links at the bottom of my post that will help you out tremendously. You MUST read the information contained on those sites if you want your beardies to stop suffering. Yes, they are in pain and suffering right now.
Your substrate has a good chance of killing your beardies as well. The labels on reptile products are not regulated and are filled with misleading information and lies. The calcium your beardies sit on can be injested but it has the potential to do a lot of harm. It can change the ph of their stomach and it also has a tendency to clump up and block the digestive system which will eventually lead to death. Try putting a bit in a glass of water and see how quickly it dissolves.
Their day/night cycles are way off as well. During the summer they should have 14 hours of light and 10 of dark. In the winter flip these numbers grudually.
The basking spot they use needs to be a minimum of 90. Preferrable 105-115 although I have heard some have it a little lower for adults but never below 90. If I were you I'd take it up to 100 minimum.
You need to get new enclosures badly. If you don't have the funds to get these things straightened out I strongly suggest you either euthenize these beardies or give them to someone who has the ability to make their lives better. Right now your beardies are dieing a long, horrible death and they don't have a choice in the matter. It's all up to you. Either you cause them to die slowly and painfully or you cause them to be happy and healthy. Whatever you choose to do is your decision but the next time you're cold, hungry and sick you think about those beardies and you'll have an idea of what you made them go through. Help them, you are their only hope right now.
Here's some good links to get you started in the right direction. On these sites there are other links and I suggest you research all of them. Spend a couple of hours reading up and making changes and your beardies will stop suffering.

I really hope I have made some sort of impact on you and that you will do what is necessary to make things right for your beardies.
I wish you and your beardies the best.
