set custom ringtone to specific contact number

Android has a special column for this: ContactsContract.CUSTOM_RINGTONE.

So, you could use ContactsContract.Contacts.getLookupUri to get your contact's Uri, after that pretty much all that's left is to call ContentResolver.update.

Here's an example of looking up a contact by their phone number, then applying a custom ringtone:

import android.provider.ContactsContract.Contacts;
import android.provider.ContactsContract.PhoneLookup;

// The Uri used to look up a contact by phone number
final Uri lookupUri = Uri.withAppendedPath(PhoneLookup.CONTENT_FILTER_URI, "012-345-6789");
// The columns used for `Contacts.getLookupUri`
final String[] projection = new String[] {
        Contacts._ID, Contacts.LOOKUP_KEY
};
// Build your Cursor
final Cursor data = getContentResolver().query(lookupUri, projection, null, null, null);
data.moveToFirst();
try {
    // Get the contact lookup Uri
    final long contactId = data.getLong(0);
    final String lookupKey = data.getString(1);
    final Uri contactUri = Contacts.getLookupUri(contactId, lookupKey);
    if (contactUri == null) {
        // Invalid arguments
        return;
    }

    // Get the path of ringtone you'd like to use
    final String storage = Environment.getExternalStorageDirectory().getPath();
    final File file = new File(storage + "/AudioRecorder", "hello.mp4");
    final String value = Uri.fromFile(file).toString();

    // Apply the custom ringtone
    final ContentValues values = new ContentValues(1);
    values.put(Contacts.CUSTOM_RINGTONE, value);
    getContentResolver().update(contactUri, values, null, null);
} finally {
    // Don't forget to close your Cursor
    data.close();
}

Also, you'll need to add both permissions to read and write contacts:

<uses-permission android:name="android.permission.READ_CONTACTS" />
<uses-permission android:name="android.permission.WRITE_CONTACTS" />
