How does this work - Curse on hit Corrupted Implicit with 3 curses

I cant seem to find the answers to some of my questions myself so I figure I would ask you fine people.

I have Hands of the High Templar with 3 curses
Curse Enemies with Vulnerability on Hit, with (48)% increased Effect
Curse Enemies with Despair on Hit, with (48)% increased Effect
Curse Enemies with Enfeeble on Hit, with (48)% increased Effect

Questions:
A) Is this not effected by the default Curse limit of 1?
B) Are all three curses being applied? if not, which one is?
C) What is the base level/quality of the curse being applied? an equivalent level 1 curse skill gem?
D) Increased effect seems ambiguous because of question C, using the increased effect value 48% what is the actual value of the curse?

Thank You :)

A) It is. Only 1 curse will end up on the enemy.
B) Curses have a priority order. Wiki has a lot of detail on the order. But in this case:
"With multiple Curse on Hit corruption implicits on the same item (e.g. Hands of the High Templar gloves, double-corrupted items), the earliest alphabetically-named curse has highest priority, up to the curse limit."
C) Level 1 curse, 0 quality.
D) You look at the value you're interested in on the wiki/level 1 gem and apply the increased % value from your mod. From wiki: "Hexes can appear as modifiers on equipment and maps, which applies the Level 1 version of the curse on the specified target. Increased curse effect listed on the modifier is relative to the Level 1 version of the curse."

Hope that helps,
