Mercen-X-Puzzles Back-n-Action

Welcome back to the X-Games... I mean, X-Puzzles. I'm back with more
mysteries. I've got one word to freely give, one fake x word made from
one real word, one real x word made from one fake word, a short list of
real x words made from real words, and a list of real x words made into
two-word phrases that tugged my interest.

Solve the fake x word and the x word made from the fake word on your own
same with the other real words.
For the two-word phrases I'll give hints and clues since they can be made
into multiple possible two-word phrases and aren't obvious.

Free Word: If you add X to the beginning of Eric, you get Xeric: Dry or lacking moisture.

Xantherel=

Each of the following words can be made into a real word containing X:
Nasty, Mire, Rise, Archer, Canthi, Alien, Hotline, Hypocrite, Osiers, Stony, Doily, Remotely, and Starchy.
