Ph.D.

Ph.D. students get 30000.

M.Sc.

M.Sc. students get 28000.

Internship

Interns get minimum wage (currently $16.75/hr).

TAship

If you TA, you should get an extra ~$5000 from that (I do not control that amount of money). I reduce the money you make from your RAship by $2000. My expectation is that students are willing to TA one semester per year.
