Yes, you can choose any two from the traditional Whitlighter powers -
Whitelighter.
NO. Whitelighter is not a power it is a race. See the link above. Whitelighters have a standard set of powers, but half-Whitelighters do NOT inherit ALL of the Whitelighter abilities. Compare that link to Wyatt or Chris's pages - they don't have nearly all the powers. And regardless,
EVERYONE CAN ONLY HAVE TWO POWERS. NO EXCEPTIONS. Telekinetic orbing and remote orbing are NOT related to
advanced telekinesis, they are related to
orbing. Nor should ANYONE have "advanced" anything at this point. If everyone were awesome and super powerful right in the beginning it would defeat the purpose of even doing this RP. Everyone starts out with 2 powers, but can develop related powers in that branch as the RP goes on, exactly like the sisters in the show did. For example, Piper started out with molecular deceleration, and at some point gained molecular combustion, then towards the very end was able to refine this to molecular acceleration. Kat and Tamora will likely develop theirs in the same way. If Wyatt has telekinesis, he can devlop advanced telekinsis later on, just as Prue did. Or if he has orbing he can later on develop telekinetic orbing, as Paige did. And by "later on" I do NOT mean in your first post. The sisters generally developed new powers during particularly stressful or traumatic times. There needs to be a catalyst for growing the powers. And in the beginning of the story, EVERYONE should be struggling and failing quite a bit.
And as a further note, we are still maintaining the importance of the Power of Three. That is why no 2 siblings can share the same inherited ability. Their powers should balance each other out, so that they MUST work together to defeat the bad guys. No one character is the star of this story - they all will have to cooperate and coordinate in order to do anything useful.
Looks great!
