Yes. You can get them from the Dream Radar game on 3DS and migrate them into Black 2 or White 2, but they can also be caught as a rare catch in Floccesy Ranch.
You cannot get Rhyperior in Pokemon emerald as he is only in Pokemon diamond and pearl.
You get your Rhyhorn to evolve into a Rhyperior.(Pokemon 188 is Rhyperior)
It learns Rock Wreaker when it is level 86.
Probably not unless you go into the global terminal with a level 100 Rhyperior and put that you want Articuno level any
Rhyperior is a 4th generation Pokemon and therefore yo are not able to attain this in fire red. Diamond and Pearl however do have Rhyperior.
