What are those names?

Code names for phones, all android builds (including official ones) have them.

For a slightly more manageable list, the 590 of those that are or were supported officially are also listed on the LineageOS wiki [1].

My device is not even listed there, so I suppose many others also run Lineage on plenty of unvendored devices.

Herolte is the galaxy s7(number 4).
