B.Tech

I'm sorry to say that you won't be able to get in any kind of government college because until now no college has taken students with more than 3000 rank. I don't know about Haryana government colleges closing limit, but if you want then you can apply there.
Best of luck.

No, chance at this rank in JoSAA counseling.

First of all, in India, the aerospace division lies in the government sector. So, for admission in those govt. companies, you need to go for competitive exams after graduation. Government companies are DRDO, ISRO, HAL, etc. Secondly, you may get placed in the educational sector.

B.Tech has much more weightage than BCA. But B.Tech is also costly and a year-long course than BCA. Which is not suitable in your case. BCA and B.Tech both the courses will provide you with the platform to get started with programming but they might not teach you exact ethical hacking. It is something that you might have to do on your own from external institutes.

ICAR is a national level exam while EAMCET is a state level exam.
