Hi & welcome! So sorry about your loss!
Your first plant is a Chinese evergreen (Aglaonema.) Here's the basic entry for that genus in the plant database here:
Aglaonemas (Aglaonema)
The 2nd pot has an umbrella plant (Schefflera,) probably this one:
Dwarf Umbrella Tree (Heptapleurum arboricola 'Variegata')
Looks like it's sharing its' pot with a parlor palm (Chamaedorea elegans):
Parlor Palm (Chamaedorea elegans)
and what's commonly referred to as a Croton (Codiaeum variegatum, your leaf looks like the 'Andreanum' cultivar):

and a dumbcane (Dieffenbachia):
Dieffenbachias (Dieffenbachia)
No idea on the fern.
The 3rd pic is a dragon tree (Dracaena marginata.)
Dragon Tree (Dracaena reflexa var. angustifolia)
Do all of the pots have holes in the bottom for excess water to escape? What windows do you have available where plants might sit near (which direction to the windows face?) Knowing what state you are in can also help folks steer you, latitude can make a huge difference in intensity of sunlight.
