I'd assume it be mostly the same with every homunculus since they are created from failed attempts at Human Transmutation which in most cases is bring someone back to life, that being said the Human Composition that can be brought with a child's allowance is probably the collection of ingredients that are used.
We can from the series confrim what was used as material for 2 of them, they are
Sloth (Ed's and Al's mother) - the human composition Ed and Al read up on which during the process we hear Ed rep.
Wrath (Izumi's child) - Izumi used her child's body as material and it was reborn as a homunculus (it was still wrapped in the sheets Izumi had it in)
as for the rest, i can only make these assumptions.
Gluttony was purposely created by Dante to use the Philosopher's Stone so he may have been created differently using different materials which would be compatible with the stone, in the movie he also shoots out Red Stones so Red Water may have been used.
Not sure about Pride or Greed on how they were made so it's not entirely sure what their Material was.
Lust was the lover of Scar's Brother and since he was a heretic already for doing Alchemy in the first place so he may have exhumed her body though it's never clear if he studied the same line of Alchemy Ed and Al used (Ishbal seems to have a similar thing to Alchemy which developed the Grand Arcanum to transmute a Philosopher's stone).
Envy was Dante's and Hohenhiem's son so we could assume the material for him was either his own remains or the same composition Ed and Al used for Sloth though there might have been something else in Envy which caused his transformation into a dragon when he passed though the gate (though this could have been because of his powers which he was using to try and get the game to take him to Hohenhiem)
