count repeats without duplicates

[excelNewbie22]

hi!
i want to count how many numbers is repeating from row2 to row 3,
and again from row 2 to row 4 - but this time if the repeated one is in here (row2:row4) and is identical to the one found in row2:row3, then ruling it out/skip it, and count only if there's new one
is it possible?

the main example is in g2:i2
