Red mage questions

[Viladin]

Thank you for your rapid response.
Does these abilities stack with weapon enchantments and materia
elemental damage enchantments?
Example
Longsword 1d8, 1d6 fire from magic enchantment, 1d6 fire from
materia, 1d6 fire from ELEMENTAL WEAPON, & 5 fire from ENSPELL.
For a total of 1d8 regular damage + 3d6 + 5 fire damage.
Sorry if i sound needy but i like having the rules clearly defined for
Ease of play at the game table and lack of strife between players.
Again thank you for your time.

Yes.
