Yes, you should be able to substitute a 7805 for the 78L05 if you are willing to do a little kludging mechanically. The L version is physically smaller and can dissipate less power and may be rated for less current. If this is just a one-off, go ahead and solder on a 7805 in a TO-220 package onto the pads intended for the 78L05.

TL072 is mainly used where high-accuracy is needed with respect to low harmonic and noise, as used for audio pre-amplification. The audio pre-amplification means for getting output audio with low noise, interference, distortion and also used for controlling the volume, bass and treble. It also compares the voltage like the other op-amp ICs do.
