Is it all just different legends mixed up or am I just confused?
Any info greatly appreciated..."

"Yep, those're Loki's six children. The first 3 you've cited were sired upon a giantess named Angerboða. Váli (or Áli) and Narfi were Loki's sons by his wife Sigyn, who was a giant goddess of Ásgarð. Sleipnir's birth is a bit strange since Loki was his *mother*! Loki transformed himself into a mare (female horse) in order to distract a stallion named Svaðilfari, which belonged to a certain giant. The stallion impregnated Loki, and the eight-legged Sleipnir was the result.

There is an even weirder reference to Loki doing something similar in the poem Lokasenna, a lot of which is taken up Loki hurling insults at his fellow gods. At one point during the exchanges, Óðinn accuses Loki of spending eight years in the form of a woman on earth serving as a milkmaid to a troll or giant to whom he, in his female form, bore children. We are not given the number, gender or names of these offspring, but if Óðinn's accusation is true then Loki had *more* than [the aforementioned] six kids."
