Some quantum experiments mention the emission
of a single photon at a time to better check the
double slit experiment.

Used in computed tomography also.

How is it possible to obtain that from a source ??

Google
"single photon emission"

Is it possible to generate of a single photon from by
exciting a single atom ??? how is it done ???

Is it a stocastic process ??? once generate the
single photon end up surely to be absorbed (or
detected) or can die out in a long run ???

You can't know very much about a single photon. You can know
stuff about a system that had a lot of photons, but the intensity
is so low it takes a very long time to accumulate them.

No evidence of "dying out".
