Venus is lost in the morning twilight and will return to the evening sky in September.
Mercury sinks towards the horizon in the evening twilight, heading towards Mars, but is still best seen with a level, clear horizon. On July 4 Mercury makes a thin triangle with Mars and the thin crescent Moon. On the 8th Mars and Mercury are at their closest.
Jupiter Jupiter was at opposition, when it was biggest and brightest as seen from Earth, on June the 11th. However it is well worth observing for some time after opposition. Jupiter is easily visible as the brightest object in the north-eastern/northern sky (aside from the Moon) and is located just below the distinctive constellation of Scorpius and the bright red star Antares. It is visible all evening long and is a good telescope target in the evening, being highest above the northern horizon around 10:30 pm local time.
Mars is in Cancer below brighter Mercury, during the week Mercury comes closer to Mars being closest on the 8th. On July 4 Mars is close to the thin crescent Moon, making a triangle with Mercury. Mars and the Moon will be visible together in wide field telescopic eyepieces if your scope can poit close to the horizon.
Saturn climbs higher in the evening sky, and is at opposition on the 10th, when it is visible all night long. Saturn is below Jupiter and just below the "handle" of the "teapot of Sagittarius. It is best for telescopic viewing from just around 9 pm local time until the early morning and is highest above the northern horizon, when it is idea for telescopic imaging, shortly after midnight.
