[MCU] what are the ages and lifespans of the different aliens in GotG?

Other than quill and rocket we don’t get any clues to how old any of the characters are and how long they expect to live.

I started to think about this when rewatching the first guardians Ronan says that his father grandfather and great grandfather have been at war with xandar. It’s supposed to be taken as they been at war for a long time but what if he literally means that they been at war for like 4-5 generations over a thousand years.

Ive never read the comics so is there any indication of how old are heroes are?

Also wtf is kraglin if he isn’t human.

In Agents of SHIELD, the Kree are shown to have very long lifetimes.  It's a plot point that the same guy has been in charge of a slave colony long enough for three generations of humans to be born, live, and die, so that no-one still alive remembers a time before he was in charge.

This particular Kree is still considered quite young by his family.
