Hello ashu, you’ve got quite a lot of problems. These problems may lead to a disaster if not taken seriously. I’ll try to help you tackle all your problems point to point so read all information I provide carefully.

For your first problem:
You said you’ve got legal documents to show you have changed your name. Are those documents in English? Get them translated by authorized personnel before submitting. If you submit these documents, there’ll be no any problem with your name change. If they ask you about it, you may simply say, you changed it because it was too lengthy.

For your second problem:
Even though you have studied up to 10 in CBSE medium and later transformed into National Open, it will not affect your visa application if your performance in both mediums where good. If your performance wasn’t much good, you may have a problem. But it would have been same even if you had done your 12th in CBSE. As university in UK has accepted you for admission, immigration officers will not enquire on your shift but they may ask you about you grades if they are poor.

For your third problem:
If your fund is sufficient to pay for at least one year living and study expenses, you may show it. But you must be able to show your sponsor’s income very strong to manage you same sum for next academic year. If your sponsor can’t show good income, you’ll not get a visa.

For your fourth problem:
If you have taken and education loan, you must show you have ability to pay back this loan. You’ll need to show some property valuation certificates as a guarantee to pay back your loan. Any hypothetical guarantee will not work.

Since, there are many doubts regarding your documents, I suggest you to ask some visa counselors to check your documents before applying for a visa.
