Any time rent is unpaid, a notice to quit should be served. The duration depends on state law.

Three months
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.
When more than one person signed the lease each is responsible for the full amount of the rent if the other refuses to pay their share. The ability to evict the co-tenant who won't pay their share varies under different jurisdictions. In some cases only the landlord can evict a tenant. You should contact a landlord-tenant agency in your area or an attorney who specializes in tenant issues.
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.
no
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.
A landlord must file an eviction through the Civil Court in order to evict a tenant.

Legally, yes.
This depends on whether the tenant's frequent calling and complaining are justified. If the complaints are justified, the landlord may not evict the tenant because of such assertion of the tenant's legal rights. Such an intervention would be considered retaliatory and may entitle the defendant damages of up to three months rent abatement. However, if it is determined that these calls are frivolous, then landlord may evict the tenant.
Yes.
