First time filing, how many of my past w-2 can I add to my 2017-18 taxes?

My mom has always claimed me on her taxes and this year since her being sick and unemployed I'm claiming  her. I have past w2 from my recent job in 2016 and 2017 and 2 others old jobs in 2016.  And I just got my new one. Can I add these w-2 to my taxes for 2018 and file them .

No you cannot.  You can only include a W-2 for 2017 in your 2017 tax return.  The tax return you are filing now is a 2017 return.  The 2018 return will not be filed until the first quarter of 2019.

If you had any tax withheld on your 2016 W-2s, you can file a 2016 return to get that back and you should have done that last year, whether or not you are claimed as a dependent.  You would simply check the box saying you were being claimed a s a dependent on someone else's return in 2016.  You would have to purchase a desktop CD to do your 2016 return now and file it by mail.  Each year's program can only file returns for the one year.
