I have a diamond ring that I got appraised which has an itty bitty piece of coal in it. The lady said it was a flaw, which is fine, but has anyone ever heard of this or know anything about it?

Diamond is not compessed coal, it is a high pressure polymorph of carbon.
The inclusion is probably graphite which is the low pressure polymorph of carbon.
Diamonds are meta stable at surface pressure conditions and can revert to graphite with a little energy input (heat).

Yes, diamonds are formed from coal under pressure. It is not abnormal for imperfections and flaws to be in the stones from the coal.

Yes, it is possible, since a diamond is compressed coal.

Yes, most diamonds have inclusions. The more inclusions, the less it's worth.
