Answer 1

Наречие yesterday может стоять либо в начале, либо в конце предложения, но предпочтительней все-таки в конце.
Yesterday dad was watchING TV - если вы хотите подчеркнуть продолжительность действия в прошлом. Если, как факт, то будет Yesterday dad watched TV
Yesterday I was playING piano at 5 o'clock. -продолжительность действия или же Yesterday I played piano at 5 o'clock. 
+
Yesterday mom cooked a tasty pie.

My friend didn't DO (his/her) homework last week.
