Autism is not a life threatening (or life-limiting) condition, and therefore has no impact upon a person's lifespan. Epilepsy can be at times life threatening and is likely to be life-limiting - however to what extend depends a lot on how well controlled the epilepsy is. According to epilepsy.com, if the person is otherwise relatively healthy epilepsy should not shorten their lifespan. Which is probably true, however (to me) it gives the slightly misleading impression that people can do things to help them become "relatively healthy", whereas what they are actually witnessing are epileptics who happen to be randomly lucky in their health.
Gaitatzis et al in their study of "Life expectancy in people with newly diagnosed epilepsy " (pubmed 15371287) conclude that "Reduction in life expectancy can be up to 2 years for people with a diagnosis of idiopathic/cryptogenic epilepsy, and the reduction can be up to 10 years in people with symptomatic epilepsy. Reductions in life expectancy are highest at the time of diagnosis and diminish with time". The fact that reduction in life expectancy reduces the further away you get from diagnoses indicates that epilepsy which is treated and well controlled poses much fewer issues than un-managed epilepsy.
Epilepsy is not fatal in its own right. Someone could die if they get a seizure in the wrong circumstances, such as driving a car or taking part in some dangerous activity. Obviously someone with uncontrolled Epilepsy should not be taking part in dangerous activities without medical advice or supervision. It is those kind of factors that have to be taken into consideration. Even if someone has uncontrolled epilepsy, they could live a long time. Someone with well controlled Epilepsy could have a seizure in a dangerous situation too. So there is no real definitive answer to your question.
Autism doesn't come in a defined state. Some have it bad, some have it lighter. Someone with a milder form can certainly live on their own.
Generally, not eating much is not good for your health. It is not a good thing to do, and for someone who has epilepsy, they need to live healthy lifestyles. That is not to say that fasting will cause seizures.
In general epilepsy is not very harmful. It does depend on the severity of it. Someone who has very severe epilepsy can encounter more problems, and may even be considered as a candidate for surgery. For most epilepsy sufferers, this is not an issue. Death from epilepsy is not unknown, but it is rare. People can also die indirectly as a result of having epilepsy, like if they had a seizure in a dangerous location and fell. Most people do not have any real problems and live very normal lives despite their epilepsy. It causes very few restrictions for them.
As of my knowledge cutoff date in 2021, the oldest person with autism in the world is likely to be someone in their 70s or 80s. It is important to note that autism is a lifelong condition, and individuals with autism can lead long and fulfilling lives.
Autism is a neurological difference, it is how the brain works and who you are as an individual. Thus for as long as you live you will be autistic.
Depending on severity, they usually live just as long as people without epilpsy.

There are plenty schools that cater to children with autism depending on where you live. Mariposa school is a school specially designed for children with autism.
It can if it effects the person enough. Someone with Aspergers should experience a normal lifespan (like anyone with autism) however if they have specific interests this can risk themselves to be in dangerous situations. Autism is not like a deformity which can certainly shortne lifespan but rather it is somethign someone lives with mentally for the rest of thier lives.
Epilepsy is not a fatal condition. Unless your friend has a very severe form, there is little risk of it killing her. The vast majority of people with Epilepsy live very normal lives.
Autism cannot be cured - Autism is a neurological difference, not an illness to be cured.A person is born Autistic and remains Autistic their entire life, just as someone who is born Caucasian cannot be 'cured' of being Caucasian. Autism is a neurological difference, you cannot get rid of Autism in a person without changing their brain, which is simply not possible.
