The presence of a sigma will be centered ( with the shared electrons) between the two atoms, such as in water H2O, the sigma will remain between the water and the hydrogen. It will remain in a bonding orbital between the two, the bonding orbital is the region where bonding electrons are likely to be found.
As far a pi bond, you know already that there needs to be sigma in order to have a pi, if you have a double bond you can assume that there is one sigma and one pi, if there is a triple bond, you can assume that there will be one sigma and two pi. That's the best way I can explain it, .

sigma bonds=9 and pi bonds=2
In a butane molecule each of the carbon forms four sigma bonds .The terminal carbon forms three sigma bonds with hydrogen and one sigma bond with carbon and the rest of the each of the carbon atoms form two sigma bonds with carbon and two sigma bonds with hydrogen .In total there are thirteen butane molecules in a sigma bond
there are as many sigma bonds as bonds (of any kind, simple, double or triple). and there is 1 pi bond for each double bond and 2 pi bonds for each triple bond.
A molecule of ethene contains 6 covalent bonds, namely 5 sigma bonds and a pi bond.
13 sigma bonds and 0 pi bonds
The diatomic chlorine molecule has 1 sigma and 0 pi bonds.
yes
A sigma bond is the bond in which two atoms share the electrons.
15 sigma 3 pi 10 lone pairs
