Hi,
1st pic: Pothos on left, the long leaning thing is a lucky bamboo (aka Dracaena sanderiana) and on the right is a Peace lily (aka Spathiphyllum)
2nd pic: a very sad Ficus benjamina
3rd pic: Crotons, a small Peace lily, and can't really see the pot in the foreground, maybe a croton in there too.

The soils look very very old, all the plants could greatly benefit from a repot into a well draining mix.
On the ficus most of the leaves are dry. How long is it in this shape? I'd say it is underwatered. Are there draining holes on the pot? Can't tell if it is salvageable or not.
Crotons could use more direct sun to be more colorful.

You have to know, there is no water schedule you can use all year around on all kinds of plants. Generally they need watering once or twice every 2 weeks. You stick your finger (or a wooden skewer) in the soil, when it comes out dry, time to water. Water throughout but let the excess water drain away, plants shouldn't sit in water. You can use bottled water or rainwater if available. Tap water can be fluorided therefore harmful for living creatures.

In the top pic, on the left is Pothos (Epipremnum.) On the right is a peace lily with 3 stems of lucky bamboo (Dracaena sanderiana) in it.

Pic 2 is a Ficus benjamina tree that looks dead. I would probably get rid of it.

Pic 3 are Croton plants (Codiaeum,) another peace lily I think, and no idea what's in the pot in the front.

All of these plants look in desperate need of being repotted. Not necessarily into different pots, but definitely a change of soil.

Here is a link that might be useful: Basic plant care info.

I'd have to agree that the Ficus is probably not worth trying to save. I'd say just pitch it.

No idea what that is supposed to be in the pot bottom front of photo #3.

I'd agree, too, that the soil in those pots looks like it all needs replaced.
