The last plant looks like a schefflera. They need lots of light and moderate regular water
Yep that's what it is,,, the plant in front of the red curtain is a dragon tree.. It's leaves should 'lift' and extend straight out ~ if you put it in front of the window but back away from it some( if you have the room,, or just slightly off to the side) it should start to lift,,
Here is mine ,,just to show you what I mean by lifting .
I have a pencil cactus
as well,, as for the snake plant/mother-in-law tongue plant,, they love to be root bound,, Last year Mine gave off a flower
,, and I have it off to the side in of a window getting indirect south lighting,, the bloom is very sweet smelling ,, here is a visual,, Just so you can see what it will look like should one spring
up in your!
All your plants look great!!!!!
