I've seen in the menus that each character, except the traveler, has a 'friendship' level. It seems to be linked to how long the character has been in the active party and, if I read right, caps at 10.
But what does it actually do?

Raising a character's friendship level:
Additionally, you will earn achievements (and therefore Primogems) for reaching friendship level 10 with 4/8/16 different characters. Check out the Genshin Impact wiki for complete information on friendship levels.
As far as I know friendship level has no effect on the character's combat ability/stats.
Friendship levels gives you the lore and the story of this world presented in an interesting way like voice lines and how they feel about stuff. The friendship mechanic mostly focuses characters lore. Each character has a story, origin, and special life lessons. So, every one of them gets a different friendship level. As of right now it does not affect combat at all.
