Can lanterns pass on there powers on to any one and if they have kids can they leave it for there child or you must be choosen the corps and how does wone get choosen

Well there power comes from the ring, so I guess they could lend the ring to somebody. But I'm pretty sure that when they die the ring choses the next host.

it's from the Ring...

when you die, the ring goes on to the next chosen lantern, or ring barer for that sector...

Rings are very rarely passed down through generations, this has only happened twice in the entire Green Lantern mythos...

How does one lose there power?

losing the ring.

But a Lantern can duplicate a ring if they posses the skill and understanding to do so. Hal has done this (Can't argue with that it happened) and so Has Sinestro.

Only Guardians can do that. And only in case of emergency.

Things have also been shown to simply be taken mid flight while searching for a new host. Mongul searched for a number of lanterns to kill them and take their rings.
