Not necessarily. In some places there is destructive interference, meaning there will be less energy, but in places where there is constructive interference, the amplitude of the wave will be up to twice the amplitude of the individual waves - and the energy up to four times as much.
Usually not. If part of a wave of a certain frequency gets absorbed, the remaining wave will still have the same frequency - and the same energy per photon.In special circumstances, due to the Doppler effect, loss of energy in a gravitational field, or to the cosmological redshift, waves can indeed lose energy in the way you describe in the question.
A standing wave consists of two waves traveling in opposite directions that interfere with each other. The nodes and antinodes of a standing wave represent points where the energy is stored temporarily and continuously exchanged between potential and kinetic energy, resulting in no net energy transfer along the wave.
The reduction in amplitude of a wave due to energy loss is called attenuation. This process leads to a decrease in the intensity of the wave as it travels through a medium and is often described in terms of decibels.
In two-dimensional wave spreading, energy loss is typically faster with cylindrical spreading, where the wave energy spreads out in a circular pattern. This is because more energy is dispersed to the sides compared to spherical spreading, which is more evenly distributed in all directions.
When a wave is reflected, the amplitude remains the same if there is no energy loss in the reflection process. However, if there is energy loss during reflection, the amplitude may change as some of the energy is absorbed or dissipated.

Absorption
It means that when the wave is reflected, not all of the wave energy is reflected - rather, part of the wave is either absorbed or simply let through.
Waves interfere destructively when the peaks of one wave line up with the troughs of another wave. This results in the two waves canceling each other out and producing a smaller wave or no wave at all at that particular point.
Intensity (brightness) and energy (frequency).
Standing wave If they do a great job, the wave practically disappears.
The wave amplitude measures the intensity or strength of a wave. It typically decreases as a wave travels further from its source due to factors like energy loss and dispersion. However, in some cases, waves can maintain their amplitude if energy is consistently added back into the system.
