There is no one group called "converts". Without being more specific (converts to Christianity, converts from Hinduism to Buddhism, etc), this question can't be answered.
Generally it is Christians and Buddhists who seek out converts, and none of the other main religions (Judaism, Hinduism, Islam.)
Nothing. Jews do not seek converts. If a person wishes to convert to Judaism, they are permitted to do so, but Judaism teaches that Judaism should not be proselytized.

No. It is part of Buddhism. Judaism does not seek "spiritual enlightenment".
Nirvana is a concept in Buddhism, Hinduism and Jainism.

If popular means "most practiced" then it is Christianity. If popular means "fastest growing" then it is Islam ( however this is mainly from birthrates and not converts). If popular means "most converts" then it is Buddhism or Hinduism. If popular means "least disliked" then it is Buddhism and Taoism (Daoism). If popular means "most talked about" then it is Atheism and Christianity.
