My Rahkshi is talking with two other Rahkshi and they both agreed to go with my Rahkshi somewhere. Is it ok to (how to say it?) move them to place I am going to? Or should I wait for their own posts about going there? I think that it's kind of unnecessary in my case.
What you propose - controlling other characters than your own in your post - is known as bunnying. It's frowned upon to bunny other characters into performing significant actions, and things out of character for them. When it's just a small thing and the other characters have agreed to do the thing you're having them do, like in your case, it's typically okay.
