I would suggest:
1. Settle city 5 first since silver is your only useable happiness res, and you need horse ASAP for chariots to help fight the barbs.
2. Right after settle the 2nd city, go Mythtcism, Mason and chop Stone Henge in capital, having stone in capital is a blessing, with a base prod of 10 you can build it in 6 turns, chop 1 tree get it for 4 turns.
3. Go for great wall in capital as well, it rids the barbs and very useful for GG spawn. With stone, chop, it should take less than 10 turns to build! If timing is good, you might get a GE from it and use him to build the Pyrimid!
4. Move your city 2 3N 1E to use the Oasis and those nice trees(wonder chop), you still get copper in it(decent prod city).
5. Settle your city 3 and make it a production city (2 food res and several hills).
6. Settle your city 4 and it is another decent production city.
7. Get those suger city if you can, if not capture it later.
7. Perhaps 1 more city in the middle of proposed city 1,2,3,4
5. Your capital is food rich, it can support some specialists, build liberary, run 2 scientists, use the GS as an Academy. You can consider turning it into a GP farm and super science city.
6. You are low on happiness, so go Alphabet, try trade for Iron working, Monochy, Math, Cal, COL
7. you have several decent production cities, so get a war going and go for a domination victory.
have fun!
