  3. If there are any licensing issues with installing those patches? (e.g. I

 patch and also need to buy out a license for using the same)

The LZW patent expires world-wide this July.

  4. Apart from 8, 16, 32 and so on, bits per sample TIFF images, are there any
 other bit per sample TIFF images possible e.g.
 1, 2, 4, 9, 17 and like wise other bits per sample images.

Many things are possible with TIFF. Particularly, for PseudoClass images, a full range of bits per sample are possible. For example, images with 5 bits per sample may be supported (but are exceedingly uncommon).
