Can i use it.. for example:

my alt claim home...
and other alt create other location home...

and this 2th alt can teleport to 1th alt character ? (or swap) ?

Transfer the map to your alt.

Then have the alt hand it to the guys in the wagon in between the church and the graveyard.

Your alt will appear at that location.

You may only do this once per character.

One time from "one character"
example...

when friend [A] give map .. i use i teleport
when firend [B] give map .. i use i teleport ?
or only ONE time ?

Any map A or B one time per each character.

Main character gives alt map. Alt uses map. Alt can never use another map again. Main character can use a map one time.

one character can use only once no matter maps of whom he got it it?

Yes.

thanks for the explanation

Is map dropable on KO ?

Yes.
