SINCE
Since is used to mean from a point in time in the past up to now. As since connects a past time to the present time, it is generally used with the Present Perfect Tense. Note that since is place before time words and phrases.
Example sentences:

• I’ve had my phone since Christmas.
• He’s been sick since last week.
• I haven’t eaten anything since yesterday.
• I’ve become more careful since I had an accident.

FOR
For is used to show a period of time. Because it is a period of time, for can be used with many tenses. Note that for is placed before the time phrase.
Example sentences:

I’ve worked for 3 hours so far to day.
I will go on holiday for 2 weeks tomorrow.
I’ve had my phone for 2 years.
I’ve lived in this city for 20 years.
AGO
Ago is used for a past time or finished time. For this reason, ago is used with the Past Simple Tense. Note that when ago is placed after the time phrase.
Example sentences:

Five years ago, I didn’t speak any English.
