Beginner Gardening: Is this jade plant dead?, 1 by DeadNotSleeping

I'm afraid more leaves have fallen out and it's looking somewhat flat. I'm leaving it where it was but I'm pretty sure it's dead.

I also believe that there are bugs in the golden barrel, near the top. I could be wrong but it looks like there are those little bugs in there. Is it too small or too young to use Amazax on it? It's about 1 inch in diameter.

Or are there any other home remedies that I can use that won't harm the little plant? With the other two cacti dying, I would really like to make sure this one is okay.

The pictures I have attached were just taken. In the golden barrel, I'm trying to show the possible bugs a bit better. The other picture is what's left of the jade plant. The full plant (if you can call it that) is right in the middle. The things surrounding it are just leaves that fell out.

Thank you for your time. Please help if you know what I can do or if you know if it's dead or not.
