I would think it's a Jade tree of some sort.
My 2 cents worth:
since they are in a glass bowl you don't want them in direct sunlight.
However, if you have them inside they should be fine, because normal window glass already filters out a lot of light, and the amount reduces drastically with every yard you move away from the window.
Even cacti can get sunburned. So you want to condition your plants slowly to brighter light outdoors. I usually start mine off on the shaded north side of my house, then gradually move them into brighter spots.
Or I place them in shade on the south side and then gradually more into direct sunlight. Overcast days are perfect for that!
Lovely plants.
