Have no idea what I'm doing...help!

[Qubes]

Hey everyone,

I am a New Yorker and have been my whole life-with that being said...we don't naturally have a green thumb. I have been wanting to grow a plant and for my birthday, my friend bought me orchids. (Beautiful but very difficult).

Here is the current state they are in. I have read to only water them once a week, not to over water. They are no in direct sunlight and I simply just don't know what to do. I am not sure how to re-pot or if I need to re-pot. Any help will be appreciated. Thanks!
