R5C9 is the only square in column 9 that can be <7>

Squares R3C8 and R7C8 in column 8 form a simple naked pair. These 2 squares both contain the 2 possibilities <59>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the column.

R2C8 - removing <5> from <457> leaving <47>

Intersection of block 6 with column 9. The value <4> only appears in one or more of squares R4C9, R5C9 and R6C9 of block 6. These squares are the ones that intersect with column 9. Thus, the other (non-intersecting) squares of column 9 cannot contain this value.

R9C9 - removing <4> from <2489> leaving <289>

Squares R2C2 and R8C2 in column 2 and R2C8 and R8C8 in column 8 form a Simple X-Wing pattern on possibility <4>. All other instances of this possibility in rows 2 and 8 can be removed.
