The first 3 look like phals, not sure about the last one. They look pretty healthy to me, not sure I would put them in an aquarium. Those plants do not really need the extra humidity. The last plant looks like it has a little red speckling on some leaves so it's probably getting enough light, just my guess.

Not sure what the last one is, but agree that these are not terrarium orchids and all would outgrow a 10 gallon tank within a year or two at their current size.
Thank you. Yeah the last one I have no idea what it is. I have never had it bloom. I just want to create a space that they can thrive in. I feel bad that they have never bloomed in years.
