These appear to be particular government aid programs. In the U.S., most such programs are developed and administered at the state or city level, so they have a variety of names, and programs with the same name may provide different benefits in different localities.
There are some federal aid programs, too. Food stamps, for example, help low-income people buy food at a lower cost. Here is a link to that program. There also is a program of federal loan guarantees for mortgages aimed at least in part at first-time home buyers. Here is a link to the agency that administers this program.
But overall, I think it is unlikely that you would find exact analogues to the programs you ask about.
