Most of this can be cleared up by working through my tutorials on improvisation.

The general principle is to find the key of the song, then target chord tones as the chords change.

The best way to figure out how to find the key & modulate to alter the scale with the chord changes is to be clear on exactly what your melody line is. Does each song have a clear melody line? Or are you just working with chord progressions at this point?

I'll answer each chord progression you've listed later when time allows.
