first time orchid owner needs help

[jeninhk]

Hey everyone,

if you didnt see my introduction i have just inherited about 40 orchids, and I am really interested in learning to care for them. (please see my intro in the breaking the ice forum)
I know most of my plants have no flowers and i know its harder to identify without flowers but what i am hoping to achieve is just a general knowledge of at least the family and what care the plant needs to survive and even flower. I believe with my untrained eye a lot of the plants need some rescuing.. so this is sort of a rescue mission he he...

So here is a start to some photos... any help would be great..
-it is really hot and humid here in hong kong at the moment
so basic care would be great...
how often should it be watered? how much light? fertilizer? what kind.. ect.. basically i dont know anything about orchids he he

Photo #1 - Any ideas what this wee funny thing is?

Photo #2- Plant 1- is it dead?
Plant 2- is it dying? i think it needs help

Photo #3- this is definitely dying.. its yellowing and has black marks... whats happening?

Photo#4 -????

Photo#5- are these orchids? and if yes they are turning yellow.. how do i make them better??

Thanks in advance!!
