Your spider plant looks very healthy. Not sure where you had it before, but I would tend to keep it there since it's apparently thriving in that spot.
Geraniums would be hard to keep indoors since they prefer full sun, here it's generally to overwinter them only. I'd get a soil moisture meter and use it before watering, you'll probably find out you've been watering them too often to help avoid root rot. Also be sure to empty the container pot of water when you water it, so it's not sitting in water, that will definitely promote root rot.
