Well, I think they are a lot better compared to what the PHB offers.
Plus you kind of missing the point of getting an extra proficiency, which at the moment means Ranger's can have as many proficiencies as a Rogue (3 from class + 1 from favourite enemy)
My view on them:
Bounty Hunter - fine as is, haven't tested the improved restrain feature. I assume it works with Ensnaring Strike.
Keeper of the Veil - good stuff, Protection from Evil and Good can come in handy at times, particularly in a setting that is heavy on abberations and fiends.
Mage Breaker - weak - would love something like the mage slayer feat - your attacks cause the target to make Concentrations saves or something. Trues Strike is pointless
Ranger Knight - good, allows you to play a strength based Ranger and dump Dex
Sanctified Stalker - weak, Sacred Flame will never out-class your attacks, plus you probably won't have Wisdom above 16. Perhaps replace it with some Cleric/Paladin utility spell?
