    Please check them all and correct.

They are OK except #5 and #7.

Although it ends in -ly, “lonely” cannot be an adverb. While “lives lonely” is technically possible with “lonely” as an adjective, it would be unusual, and for these purposes it is best to say that “lives lonely” is a mistake. (For interest, some dictionaries recognise an adverb “lonelily”. However, this is a rare, awkward-sounding word, and I do not recommend that you use it.)

Dozy,

  1. I travelled alone by myself when I was young.
  2. I travelled by myself when I was young.
  3. I travelled alone when I was young.
    Are these sentences all OK?

‘alone by myself’ is a redundancy. Use either ‘alone’ or ‘by myself’. You don’t need both.
