You have a couple options for customizing them.
The easiest and recommended way is to use the accompanying configuration file to bulk change all of the speed. Most everything has some type of configuration setting in MVNStagePackConfig.rpy, including the distance, offsets for different directions(Useful for adjusting sprites up and down when they're too tall/too short for the defaults), the duration and time of effects. The parameters are well documented, or at the very least are named in ways that should inform their purpose.
As of this writing, Line 7 has the pedestal_duration for the Pedestal (down to up pan), Line 13 has the establish_duration for the Establishing (left to right pan), and all of the zooms if you leave their zoom time unchanged will use line 18: default_zoom_time. If you change these variables in the config, it will change the timing on all of their associated premade shots.
Another way that will give you more presets while keeping the originals, you can copy and paste the transforms out of the MVNStagePackCamera.rpy and make new ones in your own files to make your own shots. For example, starting at line 51:
transform zoom_front_right:
perspective True
parallel:
ease default_zoom_time zpos -300 + zoom_front_zoffset
parallel:
ease default_zoom_time xpos 0.15 + zoom_front_xoffset
parallel:
ease default_zoom_time ypos 0.05 + zoom_front_yoffset
Lets say you like the original enough to want to keep it, you could customize this one like so to change some stuff around regarding the timing.
In your own RPY file, you could write something like this:
transform fast_zoom_front_right:
perspective True
parallel:
ease 0.3 zpos -300 + zoom_front_zoffset
parallel:
ease 0.3 xpos 0.15 + zoom_front_xoffset
parallel:
ease 0.3 ypos 0.05 + zoom_front_yoffset
This would keep all of the positional settings and just change the new timing to be 0.3 seconds vs the default 1.3 seconds.
Lets say you want to make fast versions of ALL of them, and you really don't want to go ham on having to edit each one of these 90 times.
In YOUR RPY file, try this:
define fast_zoom_time = 0.3
If you're using VSCode, you can copy all of the definitions and their transform instructions into YOUR RPY, then highlight the transform definitions ("transform zoom"), press Ctrl D to multi select lines, use your arrow keys to put the cusor in front of zoom, and just add "fast_" , then repeat this step for all of the default_ lines to replace them with "fast_".
.
Actually this was such an easy mass modification to do that, in the process of making sure I was giving you good instructions, I just.. Made it myself. Whoops. Anyway here's a 'Fast' version' Which you're welcome to copy paste and redefine in your own RPY. But I recommend you take a peek at the instructions I gave above since it'll let you make an infinite number of your own variations of your own camera shots using my preset package.

An easy and helpful modification would be to make a slow version of this. As a challenge for you or anyone else reading this, see if you can follow my above instructions to make a slow_ version of this. :D
