That´s correct. And you can even say "Şunları/Onları yedim" to make it better.

Thanks, I got mixed up, I guess I said more like ´these´.

I understand the word order can be changed with subjects, unlike in English.

Can I say for "Sam likes Lisa" "Sam Lisayi seviyor".

For "Lisa Likes Sam" "Seviyor Lisa Samı"

Sam likes Lisa:

Sam Lisa´yı seviyor

Sam seviyor Lisa´yı

Seviyor Sam Lisa´yı

Same for Lisa

If I am talking to someone, do we need ´mi´ for the question.

For example in conversation for "everyday?" can I say "her gün?" or must I say "her gün mü?".

yes, you must add ´mi´ question suffix for yes/no type questions.

You can not say "şunları yedim".

When you use "şu", you should be pointing at the object you are talking about. You obviously can not point at objects you have already eaten.

If there are pictures of the foods, you can point them on the photo

There is one more but I don´t want to mention the other possibility

Bu mesajını "Kargalar Gülüyor" !a alabilirmiyim ?

O zaman fotoğrafları yedin zannederler, akıllım !

How about "Are you working in the garden today?"

Is this OK? "Bugün bahçede çalışıyor musunuz?"

I have another one. Does Sam like döner?

Is it: Sam döneri seviyor mu?

I want to make sure that I understand then main noun forms. Please have a look.

I am going to Izmir. Izmir´e gidyorum.

I came from your house. Evinden geldim.

The child is lying on the bed. Çoçuk yatakdayı yatıyor.

Sam works with my friend. Arkadaşımla Samı çalışıyor.
