What sounds are used in Nu Disco

Hi! Can somebody help me please?

I’m trying to figure out how to make Nu Disco. And I’m wondering what type of synth is the bassline that’s playing in this mix at 6:30 min?

What type of muted guitar is playing at 5:30? And what type of lead synth is being used at 5:39?

And how do you get that aggressive piano sound at 6:45?
