7. There are a lot of many children in the park.
8. Dan and Greg are playing a soccer.

1. Who's is riding a horse? → Who is riding a horse?
   Ошибка: лишнее "is". Вопрос начинается с "Who", и это уже глагол, поэтому "is" не нужно.

2. The children are riding a bikes. → The children are riding bikes.
   Ошибка: лишний артикль "a". "Bikes" — во множественном числе, артикль не нужен.

3. Are you are having a good time? → Are you having a good time?
   Ошибка: лишнее "are". После "Are you" глагол "having" должен идти без дополнительного "are".

4. What is she Lulu doing now? → What is Lulu doing now?
   Ошибка: лишнее "she". Если имя уже указано (Lulu), местоимение "she" не требуется.

5. They's are jumping up and down. → They are jumping up and down.
   Ошибка: "They's" — это неправильная форма. Правильно: "They are".

6. Paco is watching a TV. → Paco is watching TV.
   Ошибка: лишний артикль "a". "TV" — это неисчисляемое существительное в данном контексте, и артикль не используется.

7. There are a lot of many children in the park. → There are many children in the park.
   Ошибка: "a lot of" и "many" имеют одинаковое значение, и их не следует использовать вместе. Достаточно одного из этих выражений.

8. Dan and Greg are playing a soccer. → Dan and Greg are playing soccer.
   Ошибка: лишний артикль "a". "Soccer" в данном контексте употребляется без артикля, так как это вид спорта.

В результате:

1. Who is riding a horse?
2. The children are riding bikes.
3. Are you having a good time?
4. What is Lulu doing now?
5. They are jumping up and down.
6. Paco is watching TV.
7. There are many children in the park.
8. Dan and Greg are playing soccer.
