I have downloaded landsat satellite data, then I merged the 4 bands I am interested in into one file (raster-merge). The problem is that I merged bands 2,3,4 and 8, and in the merged file the bands are named 1 to 4. The question is which band in the merged file corresponds to which individual raster band file.

I guess you are using Landsat 8 product
from my experience, it should be:
band 2 → 1; band 3 → 2; band 4 → 3; band 8 → 4
you can do band combination like RGB (3,2,1) combination and if it show natural color then its true.
4 is for band 8 which is panchromatic band
if you are still confuse, you can match the band min_max pixel values between before and after merge

ypu can compare before and after merge and see the min_max pixel values for each band. you can see the updated answer. – Uje Indo Jun 5 '16 at 5:55
