I never heard about 2 transister forward converter.
Two transistor forward converter is widely used and it's improved version of one transistor forward converter. In such converter two transistors are turned on and off at the same time. This enables to use transistors with lower Uds (2 times) voltage and also, core reset (...)

"Code for the gate pulses" suggests a microcontroller interface. Most simple method would be an opto triac, it can work for thyristors as well. Unfortunately you'll lose part of the dV/dt strength that thyristors have in contrast to triacs. A pulse transformer is the more rugged method, it can be driven through a transistor output stage. UJTs are a

Referring to the links , my explanation is as below. I would like to know whether my explanation makes sense and how can i know how the triacs works. Or someone else can provide a better explanation. How to verify the circuit works or not using LTspice?

For a cascode, the gain is approximately
= gm*ro^2 = gm * (1/(Lemda*Id))^ So if you keep the bias Id unchanged while increase the width you can boost your gain. However, large transistor increase the node capacitance hence limit the bandwidth. Run the simulation to dertermin the trade off.
Be aware not to simply increase the bias Id as gm=sqrt
