Please don’t leave used cups on the table.
请，别摆杯子上的桌子。

请不要把使用过的杯子放在桌子上。
(First, here it is no need to use the comma ',' after the word 'please', because this is a complete and continuous sentence. Secondly, you ignored the key word 'used', which means '使用过的' used to define the cups. Thirdly, the word '的' before the '桌子' is redunant, which made the sentence not fluent.)

He remembered my phone number wrongly, so he didn’t call me last week.
他记得我的电话号错，所以上周没打电话。

他记错了我的电话号码，所以上周他没有给我打电话。
(Here the adverb word 'wrongly'（错误地） is used to defined the result of the verb 'remembered'（记得）, so when you speak in Chinese, you have to put the adverb in the position of following the verb, that is '记错了'.  And there is no any subject or object in the subordinate clause, so it is confused that who on the earth called to whom, which is not mentioned in your Chinese sentence. So you have to point out the subject and object in the sunordinate clause.)

I was about to board the train when I heard someone calling me.
我差不多等上的火车的时候我听有人叫我。

在我就要登上火车的时候，我听到有人在叫我。
(Good job! You need to pay more attention to the wrongly written Chinese characters, the meaning of 'board' here is '登上', not '等上'. And you'd better add a comma between the main clause and the subordinate clause, which will make the sentence more balanced and perfect.)

He wanted to pour some milk into the cup, but the milk had gone bad.
他要倒一些牛奶里面一个杯子，但牛奶很坏。
他想把一些牛奶倒进杯子里，可是牛奶已经变质了。

(When we want to say the food have gone bad, we usually say the food '变质了' or '过期了' instead of '坏了', which means the quality of the food has changed worse and it is unsuitable to eat.)

Apart from Lao Wang, we all went to see the film last night.
除了老王，上晚我们去了电影。
除了老王，昨晚我们都去看电影了。

(Last night means yesterday night, that is '昨天晚上' or '昨晚'. There are different ways in translating the word 'last' when it is followed by the time, moment or period. In Chinese, we say last morning/afternoon/night in '昨天早上/下午/晚上', last month/season in '上个月/上个季度', last year/spring/summer/autumn/winter in '去年/去年春天/夏天/秋天/冬天', and last century in '上个世纪'. Secondly, 'go to see the film' means '去看电影'. '电影' is a pure noun, so it can not be the pradicate verb in a sentence.)

I forgot my own mobile number, I am such a pea brain.
忘了我的电话号。我很猪脑子。
我忘了我自己的手机号码。我真是个猪脑子。
(Don't forget the subject.)
