Hi Debbie, I have seen those glass globes often. The globes can still work, but you will really have to remove those tilly's and dunk them in water for about an hour during winter and allow to dry for the next couple of weeks, tip it over and then repeat, and maybe overnight dunking come the hotter summer days. I would caution though that the heat in that glass will be really hot if it gets direct sun, so make sure it is just in a bright light area and not in direct sun. It is good it has ventilation holes. These plants really enjoy all over good air circulation.
The other tilly you have, in a glass container with lid, looks like a tillandsia bulbosa, make sure you remove that lid. It needs very good air circulation. It is an epiphyte and not a terrestrial succulent. But for aesthetics, you can still keep that set-up I guess..but remove the plant and spray and mist outside or dunk it for an hour, again let it dry, tip it over so no water stays in the crown, and put it back in your nice set-up.
