Identify this plant

I got this plant in Apr 2014 and wanted to put it in a terrarium. It started well but after a few weeks, it began to rot and I managed to salvage a small portion of the plant. I have kept them for many months now and only recently, it started to grow more leaves and branches. I have no idea what is the plant's name but from the appearance of it, I think it is related to succulent plant. So when it appeared to me a succulent plant, I began to water less for this plant and put it under some shade and not direct sunlight. This has helped it to grow. Can anyone help me to identify this plant? Thanks in advance.

What is the name of this plant?
