EDIT 1.0: I study alone Latin. Those are my sentences. The translation is from English to Latin. Are they OK?

EDIT 2.0: Corrections:

1. Peter colorem caeruleum amat. - Peter likes blue color.
2. Laura fratri suo librum dat. - Laura gives the book to her brother.
3. Domus mea gilva est. - My house is yellow.
4. Ego Parisiis fui superiore septimana. - I was in Paris last week.

Answer 1

No:

• domus, -us is feminine
• Parisis should be Parisiis (abl./loc. of Parisii)
• ultima septimana is the last of all weeks (or the last week of your vacation, or whatever); "last week" = the previous week would be superiore (or proxima) septimana
