Non buffered CMOS logic gates working under load when using real components (LTSpice Sim)?

Your assumption abort default models MOS is wrong. Rds will not be zero. In fact, the default Kp parameter is very very low \$K_P = 20\mu \left[\frac{V}{A^2}\right]\$ compared to the real MOSFET that ...

How can the CMOS version of 555 timer have the output current tested at 2 mA while its maximum supply is 250 μA?

The 250 μA is the maximum at 5 V what the chip itself consumes with no load. (Note also that the 555 timer chip can produce some output current on other pins – even the other pins are unloaded in this ...

How can the CMOS version of 555 timer have the output current tested at 2 mA while its maximum supply is 250 μA?

The "maximum supply current" is only the current used internally by the timer chip. Any output current gets added to this.

Why isn't this inverter based amplifier amplifying?

You need to bias the input into the steep region of the transfer curve. Add 1M or (somethjing like that) from out to in (parallel with the first two inverters)
