来週末 (らいしゅうまつ) = Next Weekend.
筒 - tube, cylinder, gun barrel 
月（つき）moon
禁止 (きんし) = Prohibition.
蕊（しべ）= pistil and/or stamen of a flower (far far more commonly seen as 雌しべ or 雄しべ but this is one of my current favourite kanji so)
弁護士会(べんごしかい) bar association
Awww…two hearts supporting a suffering one. How sweet! 
次は一応 (いちおう) = More or Less/Just in Case.
運転手 - driver, chauffeur
Indeed, this kanji 蕊 is a worthy addition to my thread on beloved kanjis.

夜中 (よなか) = Middle of the Night.
悲しみ (かなしみ) sadness
