Pennsylvania can suspend an out-of-state license holder's privilege to drive in the state of Pennsylvania, but they cannot actually suspend the license of an out-of-state driver. They can request for that state to suspend it on their behalf, but that state has no obligation to comply.
Yes, they have the authority to suspend a license. They are the issuing authority and responsible for issuing a license. They can revoke it as well.

Illinois can revoke your driving priveleges in their state. Where the license is from does not matter.
Florida will notify Oregon to suspend your license
New York can revoke your driving priveleges in their state. Where the license is from does not matter.

It does not violate the Constitution. A driver's license is not a right, it is a privilege and can be revoked.
The answer depends on the agreement with the second state. Many do not suspend your license for an out of state violation, you would simply not be able to drive in the state that suspended you (in this case New York). NY cannot prevent you from driving in Oregon if you have an Oregon license, they can only refuse to allow you to drive in NY regardless of the state that issues your license. Oregon MAY choose to suspend your Oregon license completely, but that decision is made in Oregon.
They can suspend your ability to drive in Florida, regardless of where the license is from.
Sort of. The Ohio DMV can report a violation California. California may then in turn suspend the license until the infraction in Ohio is cleared up.
California and Arizona have reciprocity agreements, so chances are that it will. However, even if California does not suspend his driver's license, his CA driver's license may not be valid in Arizona. This means that his Arizona driving privileges on his California driver's license will be suspended by the state of Arizona. He may still be able to drive in California, but he may not be allowed to drive in Arizona.
