X-DNA matches on Gedcom

Hi all,
Can anyone help me to understand X-DNA inheritance ?
I have many X-dna matches on Gedcom.
Can we tell which are from fathers side of family, or from mother?
How about longest block, shared segments?
Can we tell how many generations back goes the connection by looking at X-DNA matches?

Many thanks
