Hello VictoriaL, they don't look bad at all.
The first one looks a variegated Snake plant to me, so it is a succulent that is just okay for its current location, just got to be mindful of your watering, it takes longer for indoor media to dry out. Whether it is a Snake plant or maybe a Yucca, it is some type of succulent that would prefer to be grown on the dry side with a a very well draining media. If it is a Snake plant, the light right now is just okay. If it is a Yucca, well, it may tolerate the indirect light too, but ideally it loves full, direct sun.
As Lin pointed out the bromeliad's mother plant, (the middle photo), will eventually go, but it will hopefully make new pups on the side. I would just cut off and remove the dried out blooms, so plant can just concentrate on growing other parts. I know with bromeliads, watering is done in the cup of the leaves, but I don't grow them much..will leave it to others input as to proper way to water them.
All of your containers, hopefully have drainage holes, so they are not sitting in water, especially the third one, the Pachypodium. You may have to consider repotting the Pachypodium in a grittier, faster draining media. This plant prefers to be on the dry side, but it actively grows during the warm months, fattening up the trunk, hence it is able to drink up very well, and go drought tolerant. Glazed containers takes just a while longer to dry up the media, so got to make your soil very well draining. I use cacti mix with lots of pumice or perlite for succulents like your Pachypodium. In a more ideal growing situation, your Pachypodium would really love to grow on the sunniest direct sun area you can provide. Typically with this succulent that stores up moisture in its trunk, or caudex I prefer to use shallow but wider containers, rather than the tall and deep ones like you have, cannot overemphasize its need to be on the dry side, having a deeper container makes dry out time far longer. But you sure can keep it in that container, take a bamboo skewer, stick it in the soil. If it comes out wet, delay watering.
