for Q1. there is more canonical forms for the product (carbocation) of the first reaction.. it is allylic as well (resonance structures more same reason) ..

for Q1 . both of you are wrong. your reasoning is only partially correct
but not totally as the resulting structure is antiaromatic , it doesn't proceed at all .
the second one has a higher k

similar arguement goes for 3 rd one.firs tis antiaromatic , second is allylic so more reactive . is 2 nd one.

as far as second one is concerned your i.e iitcoming's answer is right.

reason is that the second one gets a antiaromatic ring which is highly unstable
