Hi Harshil,
Yes, you are eligible. Just contact the concern institution for fee structure from where you want to pursue your Diploma from.

I would suggest not to go for a Diploma course after 10th, instead, go for a Degree course after completing 12th as that would offer you better career options.

According to me, computer engineering is the best in terms of scope.

SPP requirements are 6 bands, not less than 5.5 each for UG program.
