None. Fresh curry leaves are not related in any way to curry powder. Curry powder is a ground blend of different spices, not including the fresh leaf of the curry tree. There is really no good substitute for fresh curry leaves in a recipe. You could use basil leaves, but the flavor and aroma will be quite different.
Curry powder is not a substitute for dried or fresh curry leaves. Curry leaves are not in any of the curry powders. Curry powder is a mix of spices such as turmeric, coriander and garam masala. As far as I've been able to tell there is not a good substitute for curry leaves. You can add bay leaves, basil or lime leaves, but it changes the flavor. If you can't find curry leaves locally check an online Indian store.

Thai Curry uses a lot of fresh herbs as oppose to Indian Curry that uses more spices. I prefer Thai Curry as it's more aromatic and less pungent than Indian Curry. Indian Curry though is like giving a punch of flavor in your mouth. Both are equally good.
a quarter of a cup
i think equal. Experiment!
Probably four, but I could be wrong.
normally people dry herbs so that they can be stored for long periods of time without molding that and they can be ground into a powder
To enhance the curry taste in your dishes, you can try adding fresh herbs like cilantro or mint, using high-quality curry powder or paste, incorporating coconut milk for creaminess, and balancing the flavors with a touch of sweetness or acidity like lemon juice or sugar.
You are free to spice your food as you wish. Some people just like to use salt and black pepper. I have sometimes used a mixture of ketchup, mustard, and mayonnaise, which works very nicely for some dishes. You can use barbecue sauce (which comes in many different varieties) if you like. Experiment with seasoning and find out what tastes good to you.
Fresh baking powder typically has a neutral or slightly tangy smell.
