how many signals appear for the methoxy protons in 3,4,5-trimethoxyphenyl group?

Depends on your machine. With a 500 MHz upwards you should see 3 singulets. But I can imagine that you will only see 1 singlet.

Two, the 3 and 5 should be identical due to symmetry.

Orgopete is right of course. My brain was blocked yesterday ;D. The signals should have a 2:1 ratio.
