The first job (the scammer is obviously African, though the headers give no clue where he is located, the writing style does) is a mystery shopper scam. One of the businesses to evaluate is a Western Union or MoneyGram inside the Walmart or KMart, and the task consists of sending part of the money from the fake check to the scammer.
The second job is a personal assistant scam. The scammer wants someone to forward packages bought with stolen credit cards, forward money from fake checks, or buy items with fake checks and send them to him.
The third one may involve a fake check sent in advance of the job to buy tools from a fake supplier operated by the scammer.
