What is the name of these two sounds? (Lady Gaga and Zedd)

[mementus]

The first one is this, from the very first second to the second second - pa papa -


The second one is this "laser" by Zedd at 03:41 seconds


Thanks!

The first one is some kind of brassy pluck.
Try unsion detuned saws through bandpass filter. Maybe add some FM from noise.
In FX chain add some distortion, attenuate lows and highs with shelf EQ, add dotted 1/8 ping-pong delay, and some reverb.
Here is an audio example created using Serum + Replika XT + ValhallaVintageVerb:
