First of all, Don't panic!
Get yourself a cup of tea or coffee, sit back and relax.
I can't give you advise on either of these 2 orchids
Your Den. Burana Jade is a Dendrobium hybrid.
and your Rhy. gigantea is a Rhynchostylis gigantea.
I will post links to past threads on this board and a culture sheet for the Rhynchostylis gigantea .. and give you a little reading while you wait for others to respond.
Here is the culture sheet for Rhy. gigantea -
