Ok here we go
Orange 222= good bike but I personaly don’t get on with them.
Kona Stinky = not realy a downhill bike, more Freeride and so aren’t as slack and have a higher bb.
Santa cruz super8= Ok in their day but have a very high leverage ratio and most cracked.
KeeWee chromo 8= By far the best of your options but a bit heavy ( I may be bit biased as I rode a Chromozone for years!
Trek Session 10= Nice bike but very heavy.
That said if I was yust starting out I would look at the Specialized Status,Nukeproof Scalp or maybe a Canyon.
