Benzoic Acid
Formic acid is generally considered to have lower contamination levels than acetic acid, especially metal ions. Formic acid is slightly more volatile and less smelly! -DN
Formic acid is more acidic because formic acid is a smaller molecule as compare to acetic acid so polarity is working in small area and O-H bond is more polar HCOOH, in acetic acid the additional CH3- group is an electrons donor group so O-H bond is little bit stronger and less polar so it is weaker acid.
When zinc reacts with formic acid, it forms zinc formate and hydrogen gas. This is a single-replacement reaction in which the more reactive zinc displaces hydrogen from the formic acid molecule. Zinc formate is a salt and the hydrogen gas is released as a byproduct.
nothing Formic acid is already a source of H+ adding more to the solution (from another acid) would just make the solution more acidic.
Formic acid is about ten times stronger.
Benzoic Acid
Mostly formic acid. "Formic" means "ant type". Formic acid was first discovered in ants; that is why they called it formic acid. Actually, the acid doesn't get injected, only squirted into the wound made by the bite. Some ants have stings and inject poison with the sting, but the poison does not usually contain much formic acid, but more dangerous poisons.

As we know that acetic acid is CH3 substituted formic acid .since CH3 is an electron donating relative to hydrogen .so, it donates the electron to carboxyl group and makes it more negative. this phenomenon makes acetic acid weaker acid than formic acid .Thus formic acid is stronger acid than acetic acid.

Ethylamine is more volatile than methylamine.

Because it has a greater/higher Ka (dissociation constant). This is related to the ease with which the H+ can be released from the COOH group.
