Mercury will be the hardest to see as its faint and you can only see it at sunset, it will set at around 6pm. In the west where it sets, it will be slightly above the sun and to the left so just after the sun has dipped below the horizon you might get a glimpse of it if it's very clear.
The two bright ones close together are Venus (the brighter one) and Jupiter, these will set in the West like the sun and set around 8pm ish.
Around 8ish when Venus and Jupiter are setting you will be able to see Mars across in the south east, this will be in the south about 11pm. Fairly bright and reddish tinge.
Saturn doesn't rise (in the south east) till about 10pm, tonight (March 11) it will be pretty close to the Moon so its easiest to pick out tonight. After tonight it will not be directly close to the moon but you will still see it in the south east - south from 10pm till around sunrise.
