Which stocks would you pick?

Hey, my investment strategy is to monthly DCA, with 50% in long-term accumulating ETF and 50% of funds to dividend paying individual stocks. Did some research of companies I would like to own and I'd like to get your option/point of view which ones of the given duo/trio you'd pick and why.

So my picks are:

AAPL or MSFT

KO or PEP or MCD

JNJ or PFE

MPW or O

BHP or RIO

Also, in your opinion, for dividends stocks, with $500 a month, is it better to DCA and buy 5 different stocks for $100 or 10 different stocks for $50?

Thanks for anyone's input!
