It depends on the kind of Bacteria you are talking about. Most do not depend on a host and live on their own. Some, such as E. coli can live outside a host at least for some time. A few are entirely dependent on a host.
It is bacteria that can grow and reproduce without a live host
Bacteria that live in or on plant and animal tissue without harming it are called commensal bacteria. These bacteria benefit from the environment provided by the host without causing harm or benefiting the host in return.
Bacteria do not need a host organism to live and multiply.
Not really no
Facultative anaerobic bacteria.

Bacteria need a host to survive because they rely on the host's nutrients and environment to grow and reproduce. Without a host, bacteria may not have access to essential resources needed for their survival.
It`s eithercommensalism- where the bacteria is helped but the host is neither benifited or harmed. Or....Mutualism-where the bacteria and host or both benifited.You should be more specific...^.^
Bacteria are living organisms, because they can reproduce on their own without needing a host.
Bacteria lacking a nucleus
Not really no
Pubic lice can live less than a day without a human host.
Facultative anaerobic bacteria.
Archaebacteria called extremeophiles have some species that live entirely anaerobically. Bacteria [and other organisms] that respire using O2 as the 'final' electron acceptor are termed to be Aerobic, while bacteria [and the odd organism] that has the biochemical capacity to Live without O2 are termed to be Anaerobic.
Endoparasites: Live inside the host eg. Plasmodium, Tapeworm, Roundworms, Bot fly ect.
