I would suppose so, strafing would just be going left and right. Which is possible on mobile. I think that w-tap would be a bit harder since running is tapping the walk key twice (if I remember correctly) so I don't think that will work out xD
7 tap would be impossible I think, looking at the controls. And s-tap same story as w-tap.
Strafing is possible, just a bit harder than on PC, I just tested it ^-^
