Hi I am new with the harmonica can somebody tell me what are the symbols: -,> or" or the () means?. Thanks you

I am not sure that there is a standard tab format. In fact I have used different formats at different times. Anyway, I would usually consider the - to mean draw (inhale). The " usually means a two half step (full step) bend. On a C harp if you bend the draw 4 (a D note) down half a step to a C# then it would be indicted by -4'. The draw 3 can be bent half a step to Bb but it can also be bent a whole step down to A. The whole step draw bend would be -3". The half step draw bend would be -3'. Draw 3 and draw 2 are the only two places where you normally have a choice between half step and full step bends. There are also two bends in blow 10 but I never use them. Here is a chart that may help explain:

The () may mean to play the notes inside at the same time. So +(456) would mean blow into holes 4, 5, and 6 at the same time. I am not sure about >. It might be indicating pushing the slide on a chromatic.

Beads is right all the way. I would add that -3 can be bent one and a half steps. (-3"' or -3''') "Push the slide" may be indicated by > or by *.

I think beads and gene nailed it. Check out "tab guide" under resources on the left hand side of the page. In section 3 it lays out what they're saying pretty well (one symbol and its explanation on each line; easier for us visual learners). That's my go-to spot for explanation when my memory (repeatedly) fails.
