Explain it on the lease. If the tenant doesn't pay on time he can be charged a late fee (it must be reasonable) if you so state this on the lease. If the rent is really late, like let's say, 10 days, you can follow eviction procedures.

Yes: as long a you are a tenant in a dwelling at the hands of a landlord, you are renting from him and must pay rent.
Until the foreclosure sale happens, the tenant owes the rent to the landlord. What is happening between the landlord and tenant is really none of the tenant's business. And, yes, a landlord can certainly ask the tenant to pay the rent to someone else, acting as an agent. However, the tenant would be within his rights to say, "No, I'll only pay to the landlord."
If a person does not pay the previous months rent, they can most likely be evicted. The landlord can ask the tenant to leave on their own or start the eviction process.
A landlord can, at any time, initiate eviction proceedings against the tenant if he fails to pay his rent on time. Normally the landlord does this after the fifth day of default.

Some Housing Authorities will pay the security deposit as well as the first months rent for a tenant. What I mean by rent is their portion of the rent: the tenant is still obliged to pay their portion of the rent. But very few housing authorities do this.
Yes. Most landlords do want their rent money and will only allow a certain period of time, before they have a tenant evicted for nonpayment of rent.
I'm pretty sure the cosigner doesn't have to pay it. If the tenant dies suddenly, I wouldn't think his/her family would be obligated to pay the rent, because I'm sure they would move everything out when the tenant dies.
When a tenant doesn't pay his rent the landlord may begin eviction proceedings in court, which forces the tenant to move.
As you phrase the question, no the tenant is always obliged to pay owed rent. Just because they are thinking of leaving doesn't release them.
a tenant may hire any "services company" to pay their rent. A tenant only needs to start with a large deposit and thereafter, send checks to the escrow firm.
