Black carpet beetles don't bite or sting humans, so they're not harmful in that way. They are harmful to your home and possessions though. The larvae of these beetles will eat through the carpet, the padding on furniture, and fabrics such as wool and silk.
No. Beetles don't bite and they are not poisonous.
Most of the Hydrophilidae or water beetles are to small to bite, but the larger species might bite you, like beetles from the genus Dytiscus.

No, fire beetles are a type of beetle that does not bite. They are named as such because they are attracted to fire and need it to breed.
Not all beetles bite. While some species of beetles have mouthparts that can bite, most beetles primarily feed on plant material, decaying organic matter, or other substances. Generally, beetles are not aggressive and do not pose a threat to humans. However, it's always best to exercise caution around any insect.

Yes they do. It can be somewhat painful from my experience.
If color is an inherited trait in beetles and birds prefer to eat brown beetles over green ones, then over time, the population of beetles is likely to shift towards more green individuals. This is due to natural selection, where the brown beetles are more likely to be eaten before they can reproduce. As a result, the genes for brown coloration may decrease in frequency, while those for green coloration may increase, leading to a predominance of green beetles in the population.
Spiders, grasshoppers, beetles, and etc.
