In terms of morality (as opposed to current law), I would argue #1 and #2 should be legally permitted, while #3 is inconsistent and #4 should not be permitted.
Basically, as an individual regarding your private property you have total control to discriminate freely. That's individual freedom. You're allowed to choose your own guests. (Note that if you're renting a room though, that becomes a business, so this no longer applies.)
Regarding #3, as a business owner, it's necessary to create policies to be able to ban individuals based on their relevant reasons that is set as policy, which includes past demonstrated misbehavior (e.g. violence). But not because you "dislike" them. Feelings don't matter, only relevant (non-arbitrary) policies do.
Similarly for #4, again feelings don't matter. No, a business should not be able to discriminate against people who work for or own competitors. (You can ban taking photos however, since that applies to everyone.)
Basically this is all predicated on a slippery-slope argument -- as soon as you allow bans for arbitrary "dislikes" rather than "relevant reasons", you're opening it up to racism, sexism, homophobia, etc. That's the immoral part. People's desire for equal accomodation from a business strongly outweighs a business owner's "dislikes", especially as a business owner is often the exclusive one providing a certain good in a certain area.
And so this case, I would strongly argue that banning employees of a law firm which is suing you from purchasing entertainment tickets is immoral. It's ultimately no different from a Democrat-owned business banning Republicans. It's nothing more than a "dislike".
You’re suing my restaurant because you claim a patron of mine was over served by a bartender and subsequently killed someone while driving drunk.
I do not want your lawyers or their investigators or staff coming in and chatting with my staff or poking around my business without my lawyer being there.
Then tell your staff not to chat and not let anybody poke around. The lawyers may order food but not walk into the kitchen, just like literally every other customer.
Frankly if you're running a public business then I don't care if you don't want lawyers there, the same as I don't care if you don't want people of another race there. If people are coming to eat and they're not being disruptive, then serve them, end of story. It's not your private home, it's a business open to the public.

Which was not the case here. You can not summary ban every employee of a large company that's doing something you don't like.
Kelly Conlon is not involved in the case against MSG, and (as far as I understand) had no knowledge of the case.
