How do you count pi bonds on ring structures?

My teacher has given us several ring compounds and we have to determine the number of pi bonds. One ring has two double bonds and within the ring there are an oxygen with two lone pairs and a nitrogen with one lone pair. Oxygen is attached by single bonds on the ring while nitrogen is a attached by one single bond and one double bond. Does that make any sense? So its a cyclopentene but two of the carbons have been switched out with an oxygen and a nitrogen. Please HELP!

How many bonds does Sulfur forms to ahieve stability?

In terms of bonding, I see sulfur sometimes form 4 single bonds with surrounding atoms, and sometimes form 6 single bonds. How do you know which one to follow when you are given the formula for a molecule?

When does sulfur form 6 single bonds in a molecule?

Thx
Does a lone pair of electrons count as a single bond for sulfur?
