First of all, there is no reason you must choose a monotheistic religion, since there is nothing that makes monotheistic religions inherently superior to polytheistic religions such as Hinduism or some forms of Buddhism. You could, if you wish, broaden your research.
Each of the Abrahmic religions (Judaism, Christianity and Islam) is monotheistic, as are Zoroastrianism, Sikhism and others. And each claims to be the true religion. The validity of each monotheistic religion, in fact of all religions, is a matter of faith, and faith alone. In spite of earnest protestations, there is no available evidence to show that one such religion is more true than any of the others. Some say that all are false.
You should simply choose a religion that you feel comfortable with, but you will never be able to know whether that was the most 'true' choice.
Sure, there is nothing wrong with it. Sikhism is a monotheistic religion with the core beliefs being based on faith and justice. Rightness is a subjective term. Many people do not think it's right to indoctrinate young children with religion before they have the freedom to choose. It is as "right" as any religion that parents teach their children.
I don't think your religion is an issue here, it only matters that you want to be chaste. I googled - how can I get a purity ring - and several sites came up. I clicked onto the first one and found several to choose from.
they can be any religion they choose!
Every religion which choose to go to the country.
It depends on what type of person you are. Some people are raised as a member of a particular religion and never choose for themselves, whereas others may choose to become, for example, a Buddhist when their parents are christian. In other words, anyone can choose there religion at any age, assuming they have the capability to do so. As far as I know, most religions have their "coming of age" ceremonies at the age of twelve, so that is when it is generally recognized that you are mature enough to have made your own decision on which religion you choose.
