by head to tail rule they are added
Two vectors: no. Three vectors: yes.
Two or more vectors combine to form a resultant sum; V1 + V2 + ...+ Vn = VR
-- The minimum magnitude that can result from the combination of two vectors is the difference between their magnitudes. If their magnitudes are different, then they can't combine to produce zero. -- But three or more vectors with different magnitudes can combine to produce a zero magnitude.
No.
Yes, if they are pointing in opposite directions (separated by 180°).

No.
simply: No, Velocity vectors are different to force vectors. One measures velocity and one measures force so you can not simply add/subtract/multiply/divide them together and get something meaningful.
I believe the sum of two or more vectors is called a "Resultant."

You should try to visualize this yourself. Draw arrows, representing vectors, on paper; draw them head-to-tail. Try to make the head of the last arrow return to the tail of the first one. The answer is no, and yes.
Yes, if they are pointing in opposite directions (separated by 180°).
Navigators need to be able to combine the marine vessel's velocity with that of the any currents to arrive at the resultant speed and direction. This requires addition of the vectors representing the velocities of the vessel and of the current. It may also be necessary to add the wind velocity.
Gravity and velocity vectors in the proper ratio combine to make a state of perpetual falling towards the Earth that always misses
