A betta fish is named after her for the dark colors. Betta Persephone

Yes they do. They get stressed out if they don't have a hiding place. plants or caves will do.no.

It is absolutely ok to have a lamp by the betta fish tank, just make sure its not on 24/7, as fish need dark and light periods to function normally.
yes but do not pick fish that are soooo small like minnows because your betta will EAT HIM UP!
