Return SEARCHED Column Number Of Numeric Label And Value

I would like a flexible Formula to Return the Column Number of individual
Numeric Labels and their Numeric Value. I have a 2-Row by many Columns
chart/ grid layout. My 1st Column, Column Number "1" is Excel Column Letter
"F".

Numeric Label 17 is housed in Column Number "12" per my chart , its Numeric
Value 5 is housed on the next Row - directly below the Numeric Label.

Sample Data: ...

Scenario:

To Return the correct Column Number: locate the Numeric Label 17 and its
Numeric Value on the Row below, Numeric Value is 5. The Numeric Value is to
be increased by a Value of 1 (one) - NEW Numeric Value = 6. The Column
Number Returned should reflect Numeric Label of 17 remains the same but the
Numeric Value is increased by one.

To Return a Column Number representing the Numeric Label 17 and its original
Numeric Value +1 (plus one): the Numeric Label is still 17 but the Numeric
Value is NOW 6. From the oringal Column Number that housed Numeric Label 17,
that is Column Number "12", SEARCH in Ascending order: moving LEFT from
Column Number "12" and using the Numeric Value as the 1st (first) search
order and the Numeric Label as the 2nd (second) Ascending search order.
SEARCH the Numeric Value Row until the first Numeric Value either equal to 6
or more than 6 is found. Then Return the Column Number of the Column to the
Right of that Numeric Value.

Required Result:

Return the Column Number based on the Numeric Label 17 and the NEW Numeric
Value of 6, search in Ascending order - First search order based on Numeric
Value 6 - Second search order based on Numeric Label 17.

Returned Result should be Column Number 10.
