Have I selected the right funds for 10+ years investment

You have selected good funds. Please note that, all the funds that you have selected, except Mirae Asset India Opportunities Fund, are small / midcap funds. Since you have an aggressive risk profile and long investment horizon (10 years+) your fund selection will work fine, because midcap funds tend to outperform large cap funds in the long term. Among the other funds that you are enquiring about, HDFC Mid-Cap Opportunities and Reliance Small Cap Fund are also small / midcap funds. Since you already have 4 midcap funds in your portfolio, benefits of adding more funds of similar type will be quite limited. However, If you want to increase your exposure to large cap then Kotak Select Focus is a good choice.
