Well, here's my two-cents worth on a few of them:

>What is charge, why is it that we have Positive & negative charges?

There is no answer to this question...yet.  It's just a property of the
universe that some particles are charged (and there are lots of kinds
of charges: electro-weak, color, graviational).

>why the smallest unit of positive charge is equal to smallest unit of
>negative charge?

Because every particle has an anti-particle.  If you want to know why
the charge of the leptons is a multiple of the quark charges...no one
knows.  Some theories hint at this but no one knows.

>Why negative charge attaches to smaller mass than positive charge?

It doesn't.  Every particle has an anti-particle.  Negative protons
(anti-protons) are just as good as positive ones (just a bit more rare :).

>Does Anti-mater exists?

I take it you mean "do anti-ATOMS exist?".  I don't think that any have
ever been observed.  There was an article in Scientific American last
month about cooling anti-protons; soon we may be able to attach
positrons to them and make anti-hydrogen.

Natural mass (I assume that you mean macroscopic mass) spin _would_ cause
this effect if you were spinning something that was charged (most
matter has negative and positive charges that cancel out this effect).
