Any account of Dirac's bra-ket vectors depends critically on your understanding of vector spaces. Unfortunately, we have no idea as to how familiar you are with such concepts and cannot take on the task of educating you in vector spaces. I suggest you look at the Wikipedia article at https://en.wikipedia.org/wiki/Bra%E2%80%93ket_notation
Two vectors: no. Three vectors: yes.
Two vectors, no; three vectors yes.
Yes.
Assuming you want non-zero vectors, two opposing vectors will give a resultant of zero.
In vector addition, the sum of two (or more) vectors will give a resultant vector. There are a number of sites that will help you with tutorials. A link to one can be found below.
Yes, two vectors of different magnitudes can be combined to give a zero resultant if they are equal in magnitude but opposite in direction. For three vectors to give a zero resultant, they must form a closed triangle or meet at a common point where the sum of the vectors equals zero.

Two vectors, no; three vectors yes.
Yes.
vectors help in determining the direction . they give the magnitude of the number as well as the direction of the quantity

Yes, three vectors that do not lie in the same plane can give a zero resultant if they form a closed triangle. This can happen when the vectors cancel each other out due to their directions and magnitudes.
Adding two vectors results in a new vector that represents the combination of the two original vectors. The new vector is defined by finding the sum of the corresponding components of the two vectors.
Yes, two vectors with different magnitudes can be combined to give a zero resultant if they are in opposite directions. However, it is not possible for three vectors with different magnitudes to give a zero resultant because they must have specific magnitudes and directions to cancel each other out completely.
In vector addition, the sum of two (or more) vectors will give a resultant vector. There are a number of sites that will help you with tutorials. A link to one can be found below.
Yes, put the three vectors in a plane, with a separation of 120 degrees between each vector and each of the other vectors.
To subtract more vectors, you can perform vector subtraction by subtracting each component of the vectors separately. Start by subtracting the corresponding components of the vectors, i.e., subtract the x-components, then the y-components, and so on. This will give you the resulting vector.
