If Homunculus Horde leaves the battlefield before its triggered ability resolves, the token will still enter as a copy of Homunculus Horde, using Homunculus Horde's copiable values from when it was last on the battlefield.
Homunculus Horde
The token copy will have Homunculus Horde's ability and will be able to create copies of itself.
In the unusual case where Homunculus Horde becomes a copy of something else while its triggered ability is on the stack but before it resolves, the token will enter as a copy of whatever Homunculus Horde is copying. (Sometimes a horde of homunculi isn't helpful.)
