Worship that is not in public.
In private worship, the whole Bible is used. In public worship, only those parts of the Bible that are politically expedient at the moment are used.
In private homes or isolated places.
Public worship is when a group of believers gather together in a designated place, such as a church, to engage in communal acts of worship, such as singing hymns, praying, and listening to sermons. Private worship, on the other hand, is the personal and individual practice of worshiping God in one's own time and space, through prayer, meditation, and reading of scripture. Both public and private worship are important aspects of the Christian faith.

Certainly. Over history many have had private chapels in their homes / castles / etc. Saying your evening prayers, etc. is worshipping in private, isn't? You'll even find over history (recent history even) that some devote individuals have prayer benches in their private rooms - usually their bedrooms / suites for devotions. To my way of thinking - any worship should be done in private - but that's just me.
House fellowship is where Christians worship with fellow-christians in private houses and not in Church buildings.
Shintoists worship thousands of gods and goddesses, spirits and ghosts. They also believe in the reverence (not worship) of their ancestors. And they believe in demons and evil spirits to be avoided.
That depends on the area you live. Some worship in private, some do so publicly in order to aid others.
Monastic communities consist of groups of Christian men who have given up all their private possessions and lived very simply, devoting their lives to worship. These men are called monks. Female monastic communities are comprised of nuns.
