Use
These modpacks are standard 'curseforge' type modpacks, and should be compatible with the Twitch/Curse launcher as well as the recommended GDLauncher.
GDLauncher
Install the GDLauncher from https://gdevs.io/ and sign in with a Mojang or Microsoft account. In the bottom left there is a '+' icon. Clicking it brings up a "New Instance" dialog. Select "Import ZIP" and then either select the modpack from your computer or past in the URL to the desired modpack. GDLauncher will download the mods and setup the instance. Once it is ready you can click on the instance to launch the game. Right clicking the instance will give you the ability to enter the properties window, which allows you to update mods, add or remove mods, change launch settings, and even add a custom icon for the background image of the instance in the main menu. The right click context menu also allows you to go to the install folder, which you may want to do in order to copy your options.txt file over from a previous Minecraft install.
GDLauncher main settings are in the gear icon on the main menu, and this is where you can change the install location for all your GDLauncher instances.
GDLauncher does support multiple accounts, select the account in the bottom right and you can sign in to additional accounts.
