State disability payments typically are not affected by any private coverage you may have. Some private policies will "integrate" with other disability programs to make sure that you are not replacing too much of your income. Insurers don't want people making more money being disabled than working.

The disability has to be 'approved' by a panel of people, one or several of which could be medical doctors. Just because you or your employer have a 'plan' that includes disability payments doesn't mean that payments are automatically given for an injury. There is most likely a time limit imposed for such payments.
If the disabled person is receiving disability benefits from an individual Disability insurance policy then yes. Most individual and group Disability policies do have a provision that pays 3-months worth of disability benefit, if the insured dies. However, this usually is assigned to a specific beneficiary and not necessarily the disabled person's child.
No, to receive social security disability you must be considered disabled under the social security's listing of impairments.
