Just one. Post cards and regular First Class postage is the same for Alaska and Hawaii as for the contiguous states.

That will depend on the value of the stamps you have. If you have one cent stamps you will need 190 of them. If you have ten cent stamps you only need 19.
a metered postcard is a postcard that already has the stamp made into the the postcard. there is no need to put an adhesive stamp on it.
You buy a special stamp ( I did this last summer) and you need 4 for each postcard. The postcard took so long to get here I thought that the stamps were taken off and resold ( they sometimes do this). It would be faster to buy the card and carry it home to someone. The cost was less than a ruble.
Well it actually depends on the amount of the stamps. I believe 44 cents is the correct amount of money needed to mail a letter like that. I would use 1 regular stamp, and 1 2-3 cent stamp.
it depends on the stamp then you will know how many stamps you will need
3 stamps!
