Specifying a certain amount of the profits for any partner in a partnership

Q: I invested 1 million dollars with my friend who is running a chicken business. Normally, what happens is that I invest my money and we specify that 200,000 from the profits will be mine and the rest will be his. Is this permissible or is this interest? Please also explain the basic laws of a partnership in Islam. 

Sin for not wearing niqaab

Q: I am a female and I wear abaya and scarf but not the niqaab (face veil). I am trying my best to cover my body properly and have heard that the face veil is waajib, however, my question is, do I get sin if I do not wear the niqaab? I do however wear the appropriate attire besides covering my face.

Including an amount in one's zakaat calculation that one set aside for sadaqah

Q: I made an intention that a certain portion of my annual bonus will be set aside for Sadaqah and Lillah. The money is not in a separate bank account but together with my savings. I have a spreadsheet of the amount what was spent and how much is still available for charity.

Do I need to include the amount into my Zakaat calculation, assuming that I have not discharged it as charity it for a lunar year? The intention is to still discharge the money as Sadaqah or Lillah.
