I'm not an expert, but since no one has responded, I figured I'd try to help. The first is a Jade. The second looks like Haworthia. The third might be Aloe.

Hopefully someone with more experience can assist more specifically and/or correct me.

I agree the first one is Jade

Me too. And I'm no expert either, but I'm pretty sold on (2) Haworthia and (3) Aloe.

Growing succulents in a glass container (likely without drainage holes) is really not good for them. Soil looks quite dense and moist too. Succulents prefer to be in free draining mix that dries out between watering, and in very good light. Looks like that light isn't sufficient where you keep them either, especially for 1st plant (Crassula ovata). You can see that it is growing lanky and leaning, looking for the light. Stems should be sturdy and able to support themselves (weak stems are usually result of lack of light or too much moisture, or combination of both).

3rd plant could be aloe, or gasteraloe.
