A purely resistive load is one in which there is no capacitive or inductive reactance. Whe driven by an AC voltage source, such a load will have no shift in phase angle between voltage and current.
It really does depend upon what you mean by 'shift'. For purely-resistive circuits, the load current is in phase with the supply voltage. For reactive circuits, the load current will lead or lag the supply voltage; for capacitive-resistive circuits, the load current leads, whereas for inductive-resistive circuit, the load current lags. You can change the angle by which the current leads or lags (the 'phase angle') by changing the amount of resistance or reactance.
In a pure (ideal) capacitive circuit, current leads voltage by 90 degrees.

There are many phase shift oscillator circuits on the internet. Google search, `phase+shift+oscillator+schematics` and `phase+shift+oscillator+diagrams`. Generally, if you want to change the phase shift characteristics, you'll need to substitute some fixed resistors with variable resistors and depending where they're placed, you can either change the operating frequency or the waveform characteristics.
The frequency determining components in a phase shift oscillator are the series of resistive/capacitive filters on the output of the inverting amplifier. See accompanying link.
In electrical or electronic circuits, impedance can be said to have capacitive or inductive components. Capacitors cause capacitive impedance, and coils (chokes, transformers, loudspeakers, etc.) cause inductive impedance. A capacitor is said to be a reactive component in an AC circuit because it holds charge, then releases it, causing a phase shift in the output current. This phase shift in current equates to a phase shift between current and voltage. Reactive power is defined as a phase shift between current and voltage.

Because the impedance of the inductor and capacitor is not a real resistance / has an imaginary value that causes voltage and current to be out of phase. An inductor's impedance is equivalent to j*w*L (j = i = imaginary number, w = frequency in radians, L = inductance), while a capacitor's impedance is 1/ (j*w*C). The 'j' causes the phase shift.
phase shift between voltage and current waveforms. the same issue occurs with capacitors, but phase shift is in other direction. problem is most commonly associated with coils/inductors because more industrial loads are inductive (e.g. motors) than capacitive.
phase shift in integrator is 180 degrees and phase shift in differentiator is 0 degrees
There is no phase shift.
No. It depends on the inductive and capacitive reactance of the load.
