This varies from Sate to State in the U.S.
Generally, if you have a reasonable belief that life or property (yours or another's) is in imminent danger, you are allowed to use the MINIMUM level of force required to defend that life or property. If you are actually being attacked with a deadly weapon, then deadly force is almost always justified. Just because a person HAS a weapon does not always mean you were threatened by it (such as when a person is legally carrying a gun).
Because this is the internet, it is probably worth mentioning that no, you cannot use this argument when the police show up. Only a Judge, not a private citizen, can decide that they were trespassing.
I depends on your local and state laws and statutes. From my experience, a person is not trespassing until they have been informed by signage or in person they are not allowed to be in the property or area. If the person refuses to leave or returns after they have been informed they are trespassing.Added: Also, if they enter upon the property with the INTENT to commit a criminal act, they become a 'trespasser' the moment they set foot on the property.
A person may have to may up to $4,000 in fines for trespassing. A person may also receive jail time, as well.
You have the right to use lethal force to defend yourself and other people, but not property alone. If you find trespassers on your property you can detain them and order them off your property; however simply shooting a trespasser without warning when they are not threatening anyone is murder.

Jurisdiction for trespassing varies according to location. In the United States, it can be both civil and criminal, depending on the extent and type of trespass. However, in the United Kingdom, it is usually a civil matter and police don't always enforce the laws. It should be noted, trespassing is not simply one person walking onto private or closed public property without permission, it can involve constructing a building on disputed property boundaries, dumping refuse or garbage , parking on private property as well as allowing pets to trespass on private property.
Your question is unclear. If the owner of the property asks you to leave, and you do not, you are technically trespassing. There being one, two, or eighty-five businesses there is irrelevant. However, simply locating two businesses on private property, with the consent of the owner of that property, is not trespassing. If it were, shopping malls couldn't exist.
Reasonable cause to believe a crime has taken place there or is ongoing, evidence of a criminal act left in plain sight.
