I had to rewrite from English to Spanish-Please check if I did them correctly-

1.She sees them.

Ella los ve.

2. We see them.

Nosotros los vemos.

3. I invito you.

Yo te invito.

4. I invite him.

Yo lo invito.

5.She see you all.

Ella los ve.

6. He invites us.

Él nos invita.

¡excelente!'

This one has lots of possibilities and you can clarify exactly what it means by adding a prepositional phrase at the end.

Ella los ve. (She sees them OR all of you)

Ella los ve a ellos.
Ella los ve a ustedes.

Sra

1. She sees them.

To translate this sentence correctly, you need to identify the pronoun "them" as the direct object in the sentence. In Spanish, direct objects can be translated into pronouns that agree in number and gender with the noun they replace. In this case, "them" refers to a plural masculine noun.

Correct translation: Ella los ve.

2. We see them.
Similarly, you need to identify "them" as the direct object, which refers to a plural noun.

Correct translation: Nosotros los vemos.

3. I invite you.
In this sentence, "you" is the direct object, referring to a singular person.

Correct translation: Yo te invito.

4. I invite him.
In this sentence, "him" is the direct object, referring to a singular masculine person.

Correct translation: Yo lo invito.

5. She sees you all.
Here, "you all" is the direct object, referring to a plural group of people.

Correct translation: Ella os ve. (Note: In Latin American Spanish, "ustedes" can be used instead of "os.")

6. He invites us.
In this sentence, "us" is the direct object, referring to a plural group, which includes the speaker.

Correct translation: Él nos invita.

Overall, your translations are mostly correct with minor modifications needed in sentences 5 and 6.
