The one on the shelf is probably a Akari paper lantern. I have an orange one that I quite like. You used to be able to buy them from Design Within Reach or the MoMA Design Store, but I can't find them on their sites now but they're on the Noguchi site. [1] The hanging sphere one might be similar.

For those not aware of them, Design Within Reach has a lot of nice famous designed furniture and shelving, but pricey. They often have 15% off season sales though. Good place to shop if you're into the stuff seen in this blog post.

"Paper lantern" generally. Many inexpensive import shops carried them in the Before Times. Widely available now. They offer a soft ambient glow. Not ideal as a reading lamp (a bit too diffuse), but quite good for general room lighting.

Not necessarily that specific lamp, but GULLSUDARE from IKEA is the same kind.
