Nucleophilic addition will be more likely at the angle strained species so the order will be 3 membered followed by 4 5 and 6

Rate of solvolysis is SN1 reaction...and You know for SN1 reaction Rate of reaction directly proportional to stability of carbocation

yes 5 membered ring do have angle strain which is greater than 6 membered ring. 6 membered ring have least amount of angle strain
