Apple could buy any one of them, either through friendly or hostile means. Not a single one of those would make it through anti-trust. Shareholders for Cisco would love to get $200 billion for their company; the US Government would never allow it in a million years. Shareholders for Amazon would love to get $200 billion, and they'd likely outvote Bezos' family holdings to agree to the purchase. Larry Ellison would sell Oracle for $300 billion in a heartbeat, and all shareholders would agree. Intel shareholders would instantly take a $300 billion bid; the US Government would never allow that purchase either. Apple also would never be allowed to gobble up either of the telecom monsters; AT&T shareholders would take a cash + $250 billion in shares deal, and Verizon shareholders would easily sign off on a $200 billion deal.
I think Apple would love to own their own telecom network, given their love of all things integrated. The things they could probably do in owning something like Verizon's network would be astounding. It would never be allowed.
The test for antitrust is competition being reduced to the point that prices can be controlled with monopoly-like behaviour, or suppliers are cut out from supplying competition.
Applying that test to all of those companies doesn't give Apple supplier control, extensive pricing control or monopoly power in any market.
for eg. even acquiring HP would be total 'PC' market share of ~25%. The only one that may be a concern is ARM, but that doesn't mean mergers are stopped, it just means that agreements are reached (for eg. as with Google and ITAR)
Furthermore, except for AT&T, Verizon, and possibly ARM, none of those acquisitions would be strategic for Apple. Intel is doing exactly what Apple would want them to do anyway, HP and Dell offer nothing Apple doesn't already have and a bunch of stuff Apple doesn't even want, Facebook and Amazon are overpriced, Google is probably overpriced and doesn't fit into Apple's strategy, and Oracle, Cisco, and TXI don't fit into Apple's strategy either.
