The normal distribution would be a standard normal distribution if it had a mean of 0 and standard deviation of 1.
They are said to be Normally distributed.
Yes. You could have a biased sample. Its distribution would not necessarily match the distribution of the parent population.

There are many populations that would not likely have a normal distribution. Endangered species or unsocial animals would be such populations.

Generally, when we refer to the normal distribution, it is the standard, univariant normal distribution. We don't have a normal type 1, type 2, etc. However, there are closely related distributions, the truncated normal and the multivariant normal. A truncated multivariant normal would also be possible. See related links.
To the extent that your 401k distribution includes Employer contributions, a percentage of the distribution would be used to offset your unemployment benefit. If there are no Employer contributions there would be no effect on your benefits.

While the initial standard should be based on a distribution of some kind, and possibly not even the normal, each personal grade should not be based on it.

How you describe a nest of an owl is it is in a tree and it looks like a normal nest.
The normal distribution is very difficult to work with: the probability density function is not simple [I suspect that only a few mathematics graduates from university would be able to integrate it!]. The standard normal has been tabulated in considerable detail and so, if the normal is transformed to the standard normal, most of the analyses, hypothesis testing, confidence intervals and so on can be found by looking up tables.
