The measurements are not compatible. A gram is a measure of mass. A teaspoon and a millilitre are measures of volume. An ounce (unqualified) is a measure of mass but a fluid ounce is a measure of volume.
So some of these measure two different things and, according to the basic rules of dimensional analysis, conversion from one to the other is not valid.
A millilitre of alcohol, for example, will have a mass less than 1 gram but a millilitre of treacle will have a mass of more than one gram. So is a ml more than a gram or less?

There is no exact amount, just a small one. The most common measurement, however, is 1/32 of a teaspoon.
Not necessarily. A spoonful could refer to using any size spoon to scoop a certain amount, whereas a teaspoon specifically refers to a standardized measurement equal to 5 milliliters.
It is the mass of the object.
To tell the amount of something, you take a measurement.
The measurement of the amount of matter in an object is its mass. Mass is typically expressed in units such as kilograms or grams and represents the quantity of material in an object, irrespective of its volume or weight.

a milliliter(mL) is the SI unit of volume and is a good measurement for small amount of liquid
We aren't going to be able to answer this accurately if you don't tell us what the numbers are.
Ah, isn't that a delightful little measurement question? If you have one fourth of a teaspoon, and you're looking for half of that, you simply divide it by 2. So, one half of one fourth teaspoon is one eighth of a teaspoon, a tiny amount that can still bring a lot of flavor to your creations. Just a happy little measurement to keep in mind as you cook and create!
