Yo estoy nado
The word nado is incorrect because doesn't represent the conjugation of any verb. Basically, this word does not exist. The word yo is correct and is the subject pronoun for the first person singular.

Yo estoy nadando (I'm swimming)

Nosotros estamos nadandos
The word nadandos is incorrect because doesn't exist. The word nosotros is correct and is the subject pronoun for the first person plural. On the other hand, the word estamos comes from the verb estar and is correct, matching the same first person plural. Finally, the correct sentence is:

Ellos estaban hablando
This sentence is correct. The word estaban comes from the verb estar matching the third person plural in the imperfect tense.

4. False
Yo fui a Madrid todos los anos
This sentence doesn't make sense because of todos los anos. Let me explain, the word fui is the conjugation of the verb ir for the first person singular in the preterite tense. This tense is used to describe actions that took place or were completed at a certain point in the past. That is, I went to Madrid. Todos los años means every year, since the preterite tense is used when making something at a certain point in the past, you need to say something like this:
Yo fui a Madrid el año pasado (I went to Madrid last year)
5. False
El estudio cuando yo entraba
This sentence is incorrect because of the word estudio. The correct word is estudió. Don't forget to add accent mark when required in Spanish words. An accent mark can give a different meaning in a sentence. To make this sentence correct, you just need to replace estudio for estudió in the sentence. Therefore:
El estudió cuando yo entraba
6. False
El ano pasado, yo fui a Espana.
This sentence is incorrect because of the word ano. The correct word is año. Recall that in Spanish we have a letter ñ which is not part of the English alphabet. So the word año means year, The word ano has other meaning. Thus, the correct sentence is:
El año pasado, yo fui a Espana. (The last year I went to Spain)
