The police can arrest you ANYWHERE.

An apartment complex is almost always private property, with or without a gate or fence, owned by the landlord, or jointly if they are condos. Even if it is owned by the municipality, there may also be a fence or gate and access is restricted to residents and their visitors, although it is not technically "private" property. As part of the subdivision or cluster housing plans, the private apartment complex developer may have also given "dedicated ways" to the municipality, for purpose of access by emergency vehicles and other services. If that is the case, one could argue that such streets must be open to the public, even though they are still "private property". Consider, for example, that a shopping mall, and its parking areas, is also "private property", but open to the public, subject to private rules.
Car repo is covered by its own law. So No
The state of Illinois to buy private property for public use
Makes no difference what you hit. If you leave it is hit and run, or (in some states) 'leaving after colliding.' The fact that only non-moveable property was damaged is immaterial. If the mailbox wasn't just a private mailbox for the apartment, but happened to be an 'official' US Postal Service mailbox, you could, theoretically, be charged with destruction of government property.
Only on private property. They are not street-certified and are not allowed on public streets.
if it is private property yes. If you live in a complex that has security guards, you can keep them off to an extent. If its private property, I would suggest to notify them that it is private and you want them to leave. If they do not leave you have the right to call the police and have trespassing charges brought against them.
No property is really EVER abandoned. All property is owned by SOMEBODY. It may be empty and even look derelict - but it is NEVER abandoned.
It depends on whether or not local zoning / building codes permit them.

Be careful. If your vechicle has been sitting on someone's private property for very long, the property owner may be able to legally charge you a storage fee. Even if you "Steal" your own car back, they may have posted a claim against the vehicle's VIN number, rendering the car unregisterable. These fees can quickly add up to be more than the value of the vehicle, in which case you'd want to give up on that vehicle. On the up side, most property owners would be happy to have you get your chunk of crap dead car off of their property.
I googled apartment curfew and 1.9 million hits came up. the first two pages are news reports about people being outraged because apartments have done that. So I'd say probably, but it might depend on your state.
