Yes we can fight all unclean spirits (lb)

There’s none of them can withstand the authority of Christ. And The authority was given us to cast them out in His name.

Not every one is called to do that as the spirit gives us different gifts for the common good but they are all parts of the Holy Spirit. Some get the gift of prophecy, some preaching, some wisdom, some healing, some discernment of spirits, etc.

and when you can discern them— you can cast them out. You don’t have to be spiritually perfect to do it, merely spiritually strong and do it with authority.
