welcome to the forum mate

i think you might be our first person from India to join!
as for your tree unless you are going for a forest/clump i would be removing those suckers, as Kvan has said remove the top soil to find the root spread, that way you can get all the suckers out at the base and wont have probs with them popping back up! once that is done i beleive you will have to get it growing strongly, there isnt much in the way of workable branches, so you need to get it growing strong, then we can look at styling.
im not sure how hard the wood are on these but that dead wood will need a bit of clean up and then a hardener will help stop it from rotting out
i actually think it may be celtis too... was this tree tagged when you got it?
