Are These Happy Guinea Pig Sounds?

[raphael alves]

hi, i'm a new guinea pig owner

my 2 males came home 2 days ago.

when i'm feeding them carrots on my lap, they make lots of different noises and feel like running around and stuff.

they are brothers and they are really scared of me, one just eats what i have to offer when the other one does, they both trust or neither one does.

i don't know what they are trying to tell me, cause each site tells me thousands of different meanings to the same freaking sound.

so, i recorded the sounds they make while they're on my lap, can you guys tell me if i'm making them happy or if they are upset?
