Yes, they are highly reactive towards each other and their reactions are completed within 0.000001 seconds.
Buffers contain both one weak acid and its coupled weak base, that can not react with each other (they are a so-called conjugated system). When you add strong acid it will react with the base part of this buffer, when strong base (hydroxide) is added it will react with the acid.
A salt.
They create a mostly neutral mixture.
There are many things with a base could react. A base could react with an acid or foods for example.
A strong acid dissolves to form H+ and an anion, and a strong base dissolves in water to form OH- and a cation. When they react, the H+ and OH- react, forming water (and usually a large amount of heat) the anion and cation may either react to form a precipitate (if the reaction yields an insoluble compound) or they remain suspended (if their compound would yield an already soluble compound). A strong acid when react with a strong base, a neutral compound is formed with the evolution of heat.

A strong acid and a strong base will react together to produce a neutral salt. E.g., HCl (strong acid) and NaOH (strong base) will react together to form H20 and NaCl (salt). The salt is neutral (if you dump table salt into water, the solution will be neutral) this is because the Na+ and Cl- are perfectly happy being charged atoms. If you have something that doesn't really like to be ionized, which is a weak acid or base (for example acetic acid, (vinegar) which is only 1.1% ionized (charged) in a water solution) will only be ionized if something forces it to be ionized, i.e., a strong acid or base. When there is a mixture of a weak acid and its conjugate salt (or weak base and its conjugate salt) a buffer is formed. This is due to the fact that if you add some strong acid it will simply react with the conjugate salt, and if you add some strong base it will react with the weak acid. This is how they "buffer solutions" by keeping things pretty balanced. So to answer your question, a buffer must contain something that is only weakly reactive, and can react further when the need is present. A strong acid/base will totally react, so there is nothing left over to do any buffering.
No, they require a stronger, not more, acid to react fully with.
Depending on the type of acid/base (Arrhenius, Bronsted, Lewis), the acid donates protons and a base doesn't but accepts protons, or the base donates OH- and the acid doesn't, or the acid accepts a pair of electrons and the base donates a pair of electrons. They are just different, that's why.
They form water and a salt which is either soluble thus ionised, or as insoluble precipitate.
A strong base will, in water, fullyhydrolyse to give (react into) hydroxide (OH-) ions.A weak acid will, in water, partially hydrolyse to give (react into) hydronium(H3O+, or H+) ions.The strong/weak difference is in bold, the base/acid difference is itallicalized.
When a strong acid and a strong base mix, all acidic protons will react with every basic molecule until one or the other runs out. The curve for a titration of a strong acid with a strong base will change slowly at first, and dramatically when the equivalence point (where the number of moles of acid is equal to the number of moles of base) is reached. The reaction, like all acid-base reactions, is fast.
Nothing, strong (H2SO4) and weak acid (NH4+) do not react with each other.However the weak base ammoniA (NH3) will react to form ammoniUM (NH4+) ions by gaining protons from strong acid (H+)
