Yes and treasures are the only bonds that move in lockstep with 30 year mortgages. When people talk about the correlation between bond yields and mortgages those are exactly the ones they are referring to.

US Treasuries also are considered among the safest, least risky assets out there. This is true globally and has been for a very, very long time.

This is all succinctly explained in the link I posted above.

Lastly bond prices have an inverse relationship with interest rates, which means that as interest rates rise, bond prices go down. So no, when rates go up to x+5 you will never be able to find bonds that pay x+5.

Indeed, interest rates are inversely related to bond prices. And bond prices are inversely related to yields. Yields and rates are highly correlated. In fact, the way banks finance mortgages is by selling bonds. The market rate they can get on those bonds determines the rate they can offer to homeowners. So of course these rates move in tandem.

What? If the current rate is x, this means that this is the rate a bond being issued right now is paying. If the rate goes up to whatever, it means that bonds being issued right now are paying whatever.

No, there is an inverse relationship between between interest rates and bond prices. This is an axiom in the bond market. See:

Yes, I know that. We are talking about rates.

Rates on bonds are meaningless without considering yield.

Rate and yield are the same thing. Whenever I’m paying a rate, somebody else is earning a yield. Whenever I’m earning a yield, someone else is paying a rate.

They are related but they are certainly not the same thing.

Yield is a normalised rate of interest, so that bonds of different characteristics can be compared. When people say a bond pays certain interest rate, they mean the normalised rate, i.e. the yield, otherwise they would make clear they're talking about the "nominal rate", which is different. Therefore in most contexts, rate and yield are the same thing.

Anyway, the thing is if the spot rate is x% you will certainly be able to find bonds in the market that pay x% interest (=yield), regardless of the fact that a bond's yield and price are negatively correlated (an irrelevant fact, for the purposes of this discussion).
