For every country there are a set of laws that deal with the evicting of non-paying tenants. In the UK there is the 1988 Housing Act and the 'no fault' section 21 process. The procedure usually requires a court hearing.

Each state has its own rules for dealing with nonpaying tenants. Generally, a notice is handed to the tenant or sent by certified mail, then eviction proceedings are commenced in court.
I am presuming we have three components here: a landlord, a tenant, and a subtenant. The landlord in this case is presumably renting to a tenant, while the tenant is presumably renting to a subtenant. I presume that tenant has a lease while the subtenant doesn't. The tenant becomes the landlord for the subtenant. Since there is no lease (in most states subletting does not involve a lease) in this case, the tenant who is the subtenant landlord can evict the subtenant. While the main landlord can evict the tenant -which automatically evicts the subtenant -only the tenant can evict the subtenant. But the main landlord can evict all by evicting the tenant.
Whether a tenant is disabled does not have a bearing on whether he can be evicted. If a PHA has the right to evict a tenant then it can evict such person regardless of disability.
Yes, you can evict the spouse of a tenant who is not on the lease. You can evict a spouse when they are on the lease if you follow the right protocol.

Does the landlord have mental reasons or does the tenant? It's against the law for a landlord to discriminate on the basis of disability, inter alia. So a landlord can't evict someone just because he has a mental illness or disability. However if the tenant damages any property, whether it is for reasons related to the illess, he can evict.
The only way you can evict a tenant without going to court is if the tenant leaves voluntarily. Otherwise, you cannot use self help and simply go in and remove their property or change the locks. You are required to go to the landlord tenant court and obtain a court order in order to evict someone. An order will only be entered after the court schedules a hearing and notice of the hearing is given to the tenant.
A landlord must file an eviction through the Civil Court in order to evict a tenant.

Legally, yes.
Yes.
The person in the property (the tenant) will have a lease. This is a legal document which sets out how the tenant may be evicted (but can not ignore the federal or state laws that may also apply). This lease is between the tenant and the landlord (whoever the landlord may be) and it will normally specify a period of notice that the landlord MUST give the tenant if the landlord wishes to evict the tenant. So look at the lease and get an attorney if you are worried.
