Is she older or younger than Thor? Older sister? Younger sister?

Much older.

@theoneabovetoaa: @rubear:she is far,far older than Thor.

Older.

@jayc1324:how old is Angela anyway???

@goodboy6: not sure but she is Odin's first born so definitely older than Thor

yeah its hard to tell.I just finished some research and found that Thor said once that he lived when humans were using stones and wooden sticks.it could be a Stone Age which is 2.5 millions years age I think.so Angela should be much older than that.

The war against Heven started because Odin didn't want to pay them for protecting humans from the Asgardians and Angela was only a baby at the time. Of course humans were using stones and wooden sticks for a very long time, so she could still be thousands of years older, if Thors statement is accurate.

you are right but Thor also said that they lived in caves and that was in Thor God of Thunder comic at the end.

She's way older.

@dami24434: I wonder how much older.

looking back during Original Sin, she was born when humans didn't know how to speak and were fighting mammoths so she is hundreds of thousand or millions of years old.

Thor is a few thousand years old so Angela is MASSIVELY older than him.
