No in Pokémon Mystery Dungeon: Explorers of Time andDarkness and Pokémon Mystery Dungeon: Explorers of Sky both Uxie and Azelf are referred to as males, while Mesprit is referred to as a female.

Quicksand Cave.
You go to that cave where the time gear is and he/she will say that you came to steal the time gear. When you battle it i recommend you to use dark-type moves. Good luck

Why are you playing explorers of sky? You should be playing the real Pokemon games.
Yes, Arceus and Shaymin are both featured in Pokemon Explorers of Sky.
The sky stairway
Unfortunately you can get Arceus in Explorers of sky :/ The closest you get to seeing it is a statue...
Mesprit is in Quicksand Cave. You'll need to encounter her for the first time you see her, but when you go back she'll ask to be recruited.
