can someone supply some info on stellar masses of stars?

Could someone provide a rough estimate of what stellar mass ranges
these stars below could have? And also what their possible range of
their radiuses could be compared o our sun's.

Brown Darf

Hello, there, and my understanding is that the line between the smallest
main sequence star and the largest brown dwarf or "infrastar" as it
might be called is somewhere around 75 Jupiter masses or 0.072 Solar
masses. This estimate sometimes varies a bit; the sci.astro FAQ, for
example, suggests "less than 0.08 Solar masses."

The basic idea of a brown dwarf, at least in one widespread definition, is
a body which, unlike a planet, attains a sufficient mass and core
temperature for nuclear fusion of deuterium to occur -- about 13 jupiters
or, I guess, roughly 0.012 Solar masses -- but an insufficient mass to
reach the main sequence with stable hydrogen fusion (although for brown
dwarfs or infrastars near the upper limit, a brief period of hydrogen
fusion may take place).

An interesting property of brown dwarfs is that they tend to share a
similar size, comparable to that of the planet Jupiter, because the
interior is ultimately sustained by electron degeneracy pressure, as
also happens in a "superplanet" in the range of about 2-13 Jupiters.
For planets below two jupiters, and for stars on the main sequence
where sustained fusion upholds it against gravitational contraction,
greater mass means increased volume -- a different situation than in
the "superplanet" and "brown dwarf" ranges.

For the more general questions you have raised, there are various sources
on the World Wide Web. For example, one starting point is:
