You are asking a few questions that actually need a bit of clarification before they can be precisely answered:
After aborting the subscription, from the account page of AppStore
If you purchase a subscription again,
Do StoreKit add a transaction queue?
The answer actually depends on what you mean by "After aborting... purchase..again" since you turn off a subscription (aka abort) while the subscription is still active. So, if you mean "turning off a subscription and then purchasing again while the subscription is still active" then the answer is "no, there will be no transaction until the next renewal occurs and then there will be a standard transaction". But if you mean "turning off a subscription and then purchasing again but only after that earlier subscription has expired" then the answer is "yes, there will be a transaction".
Will transactions be added in the same way if a subscription is canceled by Apple's customer support?
A subscription will be added in the same way as if you had 'turned off a subscription and then purchased again but only after that earlier subscription had expired'; and in addition the receipt for the earlier purchase will have a cancellation_date field.
