| Hi rfkhky! Welcome to this nice friendly forum!
Looks like you have one dendrobium and apart from the catt, the rest all look like phalenopsis to me (others will give you more definitive id's). They all like to have temperature fluctuations over the course of a day... the catts want more sun, and while the phals probably have enough, they definitely want a coolness in the evenings to spike. Check out the cultivation and care threads on this forum! And welcome!
