Notice: I’m not a gun owner, but I have friends who own firearms, and while I have no intention now to buy a gun, I want to be able to purchase a gun in the future should I feel that the need arises.
Second Notice: While I’m applying the logic and cases from some of the other Bill of Rights amendments to the Second Amendment in the way that I think they would be applied IF politics didn’t enter into the picture, don’t be surprised if and when the U.S. Supreme Court rules totally contrary to what I write here. 
All that said, here goes:
“1.Mandatory registration of firearms”
Constitutional. Even though the First Amendment gets the highest level of protection from the courts, regulations that reasonably restrict the “time, place, and manner” of expression without regulation content or viewpoint have been upheld. Specific to this question, periodicals are required by some federal postal statute adopted during the New Deal (I don’t recall the cite) to regularly publish a disclosure of their ownership, editorship, and circulation.
I put one proviso on this: one must actually be able to register their firearm by providing the required information and a reasonable fee. If the Second Amendment were held to the same standard as the First, ordinances that require gun registration, followed up by a decision to accept no registrations except for renewals of pre-existing registrations (Chicago re. handguns), would be struck down as a sham.
“2. Mandatory licensing of firearm owners”
Constitutional, so long as the licensing isn’t so restrictive or unduly conditioned that it is a pretext – a prohibition disguised as a mere regulation. That is, if a person satisfies reasonable conditions (including minimum competency testing) set forth clearly in the law, they are entitled to receive a license.
“3.Five day waiting period.”
Reasonable time, place, and manner regulation, as long as there’s an exception to get a firearm immediately if one can demonstrate to a judge that they are under immediate threat of physical harm. This “rule” is similar to the court cases regarding ordinances that require permits for marches and protests.
“4.Two week waiting period.”
Really iffy. Is this a reasonable restriction on time, place, or manner? I personally don’t think so. And it smells of pretext.
“5.Prohibition on ownership of automatic weapons.”
“6.Prohibition on ownership of grenade launchers.”
Reasonable restrictions on time, place, and manner – you can still buy shotguns, handguns, and non-automatic rifles – so long as “automatic weapons” are defined in a manner reasonably related to the purpose of keeping high-fire-rate weapons out of the hands of people who don’t need them. An example of an unreasonably-related definition of a banned weapon – the “assault weapons” ban that banned weapons based on their appearance, not their firing capabilities, so that a rifle with a certain kind of stock is illegal while the same weapon with a different stock is legal.
Would a prohibition on handgun ownership be a reasonable restriction? I don’t think so. A rifle or a shotgun is not a reasonable substitute to the handgun for self-defense, as it is not easily carried in an accessible state on the person or in an automobile and is not nearly as useful for defense at close range.
“7.Prohibition on firearm ownership by felons.”
Clearly constitutional. Gun ownership has been recognized from colonial times as one of the civil rights restricted or revoked by a felony conviction. The Founding Fathers would have had this in mind in their drafting of the Second Amendment, and didn’t spell out such a prohibition because it was pre-existing.
