Apart from the second one, which I've never heard, these phrases are all widely known in English-speaking countries. Are they widely used? Well, yes and no. The interesting thing about proverbs is that it is very rare indeed for anyone to quote these proverbs in their entirety. What we generally do is say just the first few words. For example: 'Are you really going to drive 100 miles just to spend the evening with your mate John? 'Well, his girlfriend's just left him and he's feeling pretty fed up. You know, a friend in need.. 'Yeah, I see what you mean. There is never any need to say the whole proverb.

These 2 are commonly heard. A friend in need is a friend indeed Birds of a feather flock together Never Used: - Forbidden fruit is sweet ه - A man can do no more than he can

All are understood 1. A friend in need..... is very common so 4 or 5 2. 1-2 a more popular expression would be "there are not enough hours in the day" 3. 4-5 popular but needs the right context 4. 1-2 more popular would be to say "the grass is always greener on the other side" a reference to the three billy goats gruff a popular childrens story
