Hi Sharon,
to All Things Plants!
I agree with David, your "Ivy" is not actually an ivy but appears to be
Pothos (Epipremnum aureum) which has a common name of "Devil's Ivy". Be sure the plant is not located near a heat vent or where it will get very cold drafts; any sudden change in temperature could cause shock and leaf drop. If you have recently moved it indoors It could very well be dropping a lot of leaves due to a change in location but it should recover and re-sprout new foliage eventually. The Pothos is fairly drought tolerant, it does very well in low light situations and requires excellent drainage and air circulation around the roots; be sure your potting medium has enough aeration and drainage so that the roots don't rot and go light on water during the winter months. You can add lots of perlite to potting soil which helps with soil aeration and drainage.
Your second plant pictured is not Aglaonema but rather Stromanthe and appears to be
Stromanthe (Stromanthe thalia 'Triostar') Stromanthe prefers very bright light but no direct sun. I have one in a container in a shady corner of my yard; they require a high humidity but the leaves on my plant always seem to be ratty looking with brown crispy edges ... even with our high humidity here in Florida!
