Can I consider both friction and bearing for pile design
Can I consider both friction and bearing for pile design
(OP)
many designer only consider either friction or bearing during design. for instance, caison piles usually design for bearing, pipe piles for friction.
can i consider the both for the above piles.

In some instances you might have 99.9% friction with minimal end bearing...in other instances just the opposite. The usual case is somewhere between...with many variables controlling.
There are even cases where the end bearing must be more than the structural load on the pile (downdrag from consolidating soils pulling the pile down)

assuming the medium dense silty sands, floating piles.

loose to medium sandy soils in all cases.

For clays - with Nc only being 9, there is very little end bearing and the bulk of the load carrying capacity will be adhesion.
If one is driving to rock, the pile capacity might very well be the material property of the pile.
Anyway that's my late night take . . .
