Try using "subinstr"
e.g., 

. replace string=subinstr(string, ",", "", .)
(1 real change made)

. replace str=subinstr(string, ">", "", .)
(1 real change made)

. gen real=real(string)
(1 missing value generated)


. list

     +-------------------+
     |     str      real |
     |-------------------|
  1. |     5.3       5.3 |
  2. |   hello         . |
  3. |       2         2 |
  4. | 2500000   2500000 |
     +-------------------+
