Some things happened to me and I really dont know if it makes my namaz baatil or no.

1) If I am about to do my massa of feet, and then my wet hands touched one part of my foot(below toes), and after that I made massa from my toes.
Its still okay?

2) When I am performing sajda during prayer, and my hands slides, its still valid?

3) Also, If during sajda, my both feet are not aligned makes my sajda batil? Like one is behind another
And do I have the right to move to do it correctly?

4) If I move intentionally my hands or my feets while performing sajda makes my namaz baatil?
