Would you be able to use telekinesis to move a figure, the target the same figure with another figure with telekinesis and move them another 8 squares?

Yes. There is nothing preventing the same figure from being targeted with telekinesis twice. (And i fixed your wording from "move" to "place." Small difference grammatically, big difference as a rules term.)

Thank You for clarifying for me! (as well as the corrections)

Its called sling-shotting.

Something I do often. TK got bashed since the new rules change but it's still highly effective.

TK is better than ever with the new rules if you know what you're doing. Letting it *place* figures instead of moving them is by FAR worth the trade-off for more restrictive LOF, and that's not even including its new Stealth-busting capabilities too.

^^^^^Someone who knows how to use TK.

It remains one of my favorite powers. I almost never go w/out it.

Slingshot to Gem/Key for a quick roll. Fantasmic.

I was about to post this as a question as well, but then I saw you mentioned it, so I will just keep it all here. How does telekinesis work when attacking stealth? I understand that you are targeting the "Square" and not the character, so how would you roll to attack?
Thanks in advance!

When designating an object as A and making an attack, the
only line of fire required is to square B. The attacked
character does not have a line of fire drawn to it and, as
such, would not benefit from a hindering terrain bonus
(even if the target is using Stealth while occupying
hindering terrain). It is still a target of a ranged combat
attack, though, so powers like Energy Shield/Deflection,
Shape Change and Super Senses would still activate.

What MoomPix wrote there^ is taken straight from the Player's Guide (just so you know that it's official and not just his interpretation).

Huh! So TK after TK is now allowed again?

Interesting!

A character with TK still can't use TK after being TKed.

It was always allowed.

What you may be think of is that a character couldn't use TK after it was TK'd. And that rule is still in effect (see VanisherPunisher's post).

Oh! Yea! Gotcha!
