No, because each and every transaction gets validated over the network by each peer using the clients (be it core or electrum or any that needs to download the whole blockchain). Why would anyone use this technology at any cost and why would Bitcoins be so trustworthy if such vulnerable possibilities would be there? There's nothing that can be done except double-spends.

Blockchain is a ledger that is completely locked block-by-block bit-by-bit and can not be touched nor manipulated at any cost.

Do you mean the transaction, or the history associated with the transaction? As has been mentioned, the transaction is immutable, but any history associated with it may be recorded in Google, and it may be possible to persuade them to delete their records.

Double spending, if successful, also doesn't delete older transactions, simply invalidates them. And this only from the point forth on the new valid chain. Anyone wanting to double spend to invalidate a certain tx would have to do it really quickly, or even prepare the attack before the tx... preempting the tx otherwise even a successful attack would still contain the tx made before the point of attack.

By any means, I never told them that double-spending gives anyone the ability to delete or manipulate blockchain. It was just for information purposes only. Though double-spending is a disadvantage, it also cannot be considered a vulnerability to the entire blockchain system. The blocks validated by miners are so secured, because the whole network needs to go block-by-block in order to get each of their future transactions validated in upcoming blocks, so the older blocks have no such probabilities howsoever that they can ever be teased.

Definitely not. That would go against the fundamental properties of blockchain. Transparency is one of the reasons why people trust the system. So, having the ability of easily deleting old transactions would mean it's flawed.
