I have taken the circuit above from a “DIY Pong” tutorial. The circuit generates the HSync and VSync for a PAL signal.
What are the labels for classification of an IC equivalent of this?

There are still sync generators such as NTE7049 available that do both NTSC and PAL.
If your video requirements are simple (with no color) then you'd be much better using an entry level MCU such as the Arduino Nano with the TV.out library. It can even be done in an ATTiny85.
If 'Pong is your end goal, you could look at this composite implementation on the Raspberry Pi Pico RP2040.
All three of those parts are currently available from stock. Eg.
TLC555IDR (SOIC-8), CD4040BM96 & MC14538BDR2G (SOIC-16)
U3 is not specified as to family etc., but 74HC08 or CD4081BNSR are suitable quad AND gates
It is easy to duplicate the function with a microcontroller, of course.
